Cornerstone Physiotherapy

Went to Luke Gregg with some shoulder and hamstring pain from rock climbing, and he was a huge help! He understood my goals since he is also a climber, was really attentive about my concerns, and was understanding when I said I had limited funds. He worked with me to make sure I could develop a good home program and was efficient so I didn’t need to have a lot of appointments. Overall great experience!

Fantastic! Very easy to make an appointment and adjust the schedule. Very good treatment at the reception. Luke, the physio, a very good professional, solved my neck pain problem in 2 sessions. Totally recommended.a 10!

I developed terrible vertigo and wasn’t able to move or eat solid food for over 24 hours. Cole provided vestibular physiotherapy the next day and I felt immensely better right away. I was able to move and eat from then on. Cole’s care and attention were excellent and I am very grateful.

It would be much more helpful if the receptionist could confirm the insurance balances before the session starts (and not at the end).

Jordon is professional, knowledgeable and, importantly, empathetic! He knows how to motivate his clients, combining clinical insight with a gentle sense of humour. I have referred him to many friends and colleagues, all of whom have been similarly delighted to work with Jordon at Cornerstone Physiotherapy.

Great help from Thomas, we went through the rehab in two phases. The first phases focuses on activating and strengthening the muscles. The second part focuses more on brining me back to my sport. Thomas did spend time picking up the rehab exercises suitable for my sport and examining my ability to see if I am good.

Had a great experience at Cornerstone. Dr. Jordan helped me with my shoulder and arm pain and movement, went from 0 to 90 degrees (literally)!

I highly recommend this physiotherapy clinic. Luke, one of their practicioners is very knowledgeable and couldn't be more personable. I have complete trust and confidence in Luke's hands.

I’ve been working with Cole Keddie at Cornerstone Physiotherapy for a few months now for problems with spinal stenosis. Cole is thoughtful, friendly, knowledgeable, and supportive. He’s making an enormous difference in my physical and mental wellbeing. I’m so glad I found Cole and Cornerstone!

I have much relief from my leg pain after one session with Luke and he found out the cause of my pain.

I engaged with Cornerstone early Spring 2023 after have a severe vertigo episode. Because of the potential delays going through my family doctor, I contacted this organization and was able to get an appointment within days with Cole Keddie - this included both an assessment & treatment. After about 2 to 4 weeks I was able to feel more "myself". I also received PT for a shoulder and groin issue. Both were better, enabling me to do the activities I want to do without limitations (including a long bike event). Cole was fantastic - friendly, knowledgeable, and responsive to e-mails. I was happy how much he could get done within the time allotted without feeling rushed. I also wanted to acknowledge the office administrators, who were also fantastic from the organizational and greeting side of things (both the Sheppard/Yonge & College locations). If you have the resources I highly recommend these folks!

Cornerstone and Jordon have been fantastic! I've worked with him on a number of issues and he's helped me work through each of them. Would highly recommend!

I was sceptical about physiotherapy for a torn rotator cuff but my doctor highly recommended the services of Cornerstone. With hesitation, I went to my 1st session with Luke Gregg. What can I say? I was not only pleasantly surprised but Luke hit it right where it hurt and did amazing things! He prescribed a series of exercises which assisted but did not cure the shoulder. Not an any fault of Luke! He was amazing and would highly recommend Luke for your services.

Since I started seeing Cole Keddie at Cornerstone Physiotherapy to diagnose and treat a number of elbow tendon related problems I've encountered as a climber I've seen significant, positive improvements.

Cole was methodical, patient, professional, and personable. He's given me a toolbox of relevant exercises to treat injuries and prevent further ones.

I've been struggling with climbers-elbow for years, and finally feel like it's manageable. Thanks!

Excellent professional service from Alex. Very good interpersonal skills, and he makes good use of our appointment time

Physiotherapy with Luke was an amazing experience. Having suffered from chronic back problems, the programme developed by Luke provided pain relief as well as improved mobility. On top of being an excellent professional, Luke also has an amazing personality and a great sense of humour.

I was referred here by a specialist for a neck and shoulder injury, likely caused by a pinched nerve. Luke was exceptionally helpful and congenial in coaching me to health; the exercises he assigned successfully restored range of motion and strength in the affected area. Cornerstone was also very gracious when I had to miss an appointment and did not charge me a fee. The location right by College station was also quite convenient.

Had an IT band injury in my right leg that prevented me from running. Ala's treatment got me back into running shape in less than 3 months! Highly professional and excellent quality physiotherapy clinic in general.

I highly recommend Cornerstone Physiotherapy. In fact I have sent 3 friends here in the last year.
Luke Gregg helped get me back to a great place in my life. I can't thank him enough for his expertise, patience, encouragement and professionalism.
Moving forward, I now have the tools and exercises to keep my back strong and move with confidence.
Thank you, to all the great staff at Cornerstone Physiotherapy.

Highly recommend! I appreciated the responsiveness and professionalism at this clinic. I was always able to get appointments that suited my schedule and am so grateful to Ala for fixing me up and leaving me with exercises that I do each day.

I would recommend anyone that needs physio to come here. I worked with Luke for many months and he really taught me a lot about my body!

Amy at the Yonge and Carlton location was phenomenal. Very professional, on time and set me up well for giving birth through the work we did together in pelvic floor therapy.

Injury assessment and therapy by Jordan was great! I highly recommend him for any sports related injuries.

Cornerstone Physiotherapy has a very knowledgeable and friendly staff. I had the opportunity after suffering a stroke to be in the hands of a very excellent professional physiotherapist Luke Gregg. I felt he really cared about and listened to my concerns. I have never had a better Physiotherapist in my life. He is a very dedicated Physiotherapist and wonderful human being! He definitely assisted me through a difficult time. Thanks Cornerstone Physiotherapy for taking such concern of my health. Jairo Sepulveda

Alex Restrepo gave me my life back. In the midst of pandemic isolation I was debilitated due to a herniated disc and excruciating sciatic nerve pain. I couldn't sit, and could barely stand or walk. Alex worked with me through video consultations and throughout the course of a few months brought me to a complete recovery. He is a patient, focused and highly knowledgeable clinician who truly understands what needs to be done in order to get results. I can't recommend him highly enough.

Cornerstone is a very professionally run clinic with personable staff and an excellent appointment reminder system.

Incredible physiotherapy clinic - I worked with Daniel Zackodnik for primarily a shoulder surgery recovery, as well as an ankle sprain, and he was thorough, insightful, compassionate, and just all around kind. Would even go out of his way to send me useful research articles on recovery. Would highly recommend.

As in the past, my experience this time with Cornerstone was excellent. Thomas, my physiotherapist, was personable and efficient. He helped me achieve my goal, which was to recover from sciatica in my leg as quickly as possible so as to be ready for hiking on my upcoming vacation. The exercises he prescribed were straightforward, very helpful and easy to incorporate and continue in my regular workout routines.

Came here for 2 issues and my physiotherapist, Amy was able to support me with both! She had a great understanding of my injuries and provided me with exercises that extremely helped increase my pain, mobility, and strength. She was super helpful in finding resources relevant to my rehab and my goals. I would definitely recommend to others looking for a great pt.

I'm posting this years after I got my issue resolved as the physiotherapist here helped me solve a very significant C6/C7 disc herniation issue. I had severe pain/burning around my upper right shoulder area so I first went to the emergency room at Sinai hospital. Sinai said I had a strain which I knew was 100% incorrect. So then I went to Cornerstone as it was close to my condo and the online reviews were good. Thankfully, the physiotherapist (I forgot her name now) was quickly able to tell that I had nerve damage due to a herniated disc. Low and behold it was confirmed by NCS and EMG that I did in fact have nerve damage. Thanks a lot for helping me figure out this issue that the doctor at Sinai mis-diagnosed.

Great physio centre. My therapist Jordan assisted me with not one but two difficult painful injuries when I felt like there was no hope. A straight forward plan for recovery, session therapy and the at home exercises which are demonstrated in an easy to use app really changed my life in short amount of time. I am very grateful!

I was experiencing severe lower back pain due sciatica and that had hindered my daily activities and chores. Amy was my therapist and she was the best! She put together a great plan for my everyday exercises and gave such simple alternatives to daily chores that I was almost back to normal in a couple of weeks. She’s knowledgeable, patient and works with you! All in all she’s a great therapist! Definitely recommend her at Cornerstone!

I have had prolonged issues with my neck, shoulder and shoulder blades due to very long hours working at a computer for many years. I have been getting persistent knots, inflammation and a lot of pain in those areas that would not go away. Working with Daniel Zackodnick at Cornerstone Physiotherapy has been a great experience. He is very careful and patient and always explains everything thoroughly. After a couple of months of visits, my range of motion has improved and pain subsided following hands-on work and the individual programs created by Daniel with targeted stretches and strengthening exercises. I highly recommend this place, the staff is polite and kind and the location at Yonge and College Street is very convenient.

Came here with hip pain resulting from a sports injury.
Amy was great and I was back to playing sport pain free in just a few weeks.

I've had treatments from four physiotherapists over the last many years, for various injuries or conditions. (I'm now in my 70s.) These people have all been thorough, professional, and most importantly, *effective. * Most recently Alex Restrepo brought knee bursitis, inflexible back, and tennis elbow back to 98-100% pain-free function through office visits and prescribed home exercises. I highly recommend Cornerstone.

Cornerstone Physiotherapy has been a fantastic resource for me while recovering from a bruised rib. My sessions with Alex have been instrumental in restoring strength and mobility, as well as decreasing pain and general soreness in my problem areas. Booking has been simple and accommodating, with reasonable prices and convenient location. I highly recommend Cornerstone and Alex in particular due to his friendly and extremely helpful demeanor. 5 bloody stars.

My physiotherapist Ala, at Cornerstone, provided the most attentive, knowledgeable and caring service. I saw her over the course of several months for a long standing neck and shoulder issue, a piriformis issue and then a herniated disc in my lower back. Ala provided excellent treatment plans that fit well with my schedule and fitness regime, continually monitoring my progress and making any necessary modifications. She is utterly delightful to work with. But what was truly above and beyond the call of duty were her email check ins and inquiries when she was unable to attend at the office due to an unforeseen family crisis. At a time when she should have been attending to her personal and family needs, she took the time out to ensure that my pain levels were being managed and to inquire about my needs and well-being. She is truly a remarkable health-care provider.

If you go to CornerStones.choose Laura Panta!: D

I am so *incredibly thankful* to have met and worked with Laura Panta over the course of my Golfers Elbow Rehab. Not only is she knowledgeable and well versed, she is also an amazing human being and very nice to talk with! I have gone to other clinics in hopes that they could help me with my injury but they did nothing in comparison to all the hard work Laura put forth. She really puts out a great effort to listen to all your concerns and then sets forth plans of action and exercises, which make a world of difference. I am a full time musician, so it was imperative that I regain control over my injury ASAP, and she really went above and beyond. *I cant thank you enough* for all your help in my healing/strengthening process and I am so very grateful to have chosen Laura at CornerStones.

I know if one day, I need to find physiotherapy again, I will choose CornerStones. (knock on wood though haha)

-Robbie!: D

I've been going to Cornerstone on Carleton for years (since Adam was doing physiotherapy himself!). This is the first time I've worked with Jordan and I found him very engaged.
He was always thinking about what else could be done to improve my situation. When our sessions came to an end because my issue had been resolved, he continued to reach out to make sure things were still going well. I will always recommend Cornerstone!

Highest recommendation. My physiotherapist Alex was knowledgeable, kind, and encouraging. The treatment progressed at a pace that was helpful and manageable by me. The staff were always helpful and efficient.

I came in on crutches with two badly sprained ankles. From Day 1 Alex was caring, informative and above all gave me the tools and confidence to push through my recovery. I always felt comfortable asking questions and expressing my concerns. Even when it came to complaints about back pain, or hip pain that may or may not have been directly linked to my injury, Alex took the time to give me exercises and tips that would improve my overall health. On top of that, the reception staff were always super friendly and welcoming at each visit. It sounds like such a small thing, but I was always surprised they each remembered my name. I would 100% recommend Cornerstone Therapy.

I have been seeing Philips for a month for my backpain and our sessions are helping me to regain my mobility and strength. Clean place, welcoming staffs. They maintain Covid protocol. They send a reminder message to your phone 45 minutes before your session which help me be on time. Kudos for the reminder.

I have rated 4 star just because their direct billing to insurance company is not working. I have insurance from Manulife and cornerstone is on provider list. It’s been a month yet the problem isn’t solved yet. It kinda giving me a headache, I am afraid I might have to pay from my pocket and then claim it back from Manulife. One of the reason I choose cornerstone was the direct billing option and it isn’t working for me. I hope they will fix the issue soon.

I came to Cornerstone barely walking. I was fortunate to be paired with Alex Restrepo. He made me feel comfortable, listened to my concerns and provided detailed instructions on how to perform the exercises to build my strength and helped me make adjustments when needed. He always encouraged and challenged me to do more. As well as providing me with physical therapy, he spent the time to talk me through set backs and obstacles that held me back. I always walked out feeling more positive. My thanks to you, Alex, for sharing your wealth of knowledge, your patience and understanding. 100% recommend Cornerstone and especially Alex. Everyone at the College street site was friendly and made me feel at ease.

My experience with Cornerstone was terrific. My elbow had been bothering me for over a year, but Amy got me completely sorted out within a span of six weeks.

I had injured my back this past summer and reached out to Cornerstone @ Yonge & College. I set up an appointment with Alex. On my first, of several sessions, I immediately felt relaxed and greatful of how Alex approached my situation. He lead me through all of my sessions with care and concern, with 'take-a-ways' on each session on how I could help heal my back. Alex is truly an asset to Cornerstone. On the road to recovery, all thanks to amazing Alex.

Excellent and friendly staff always ensure your physio needs are met. I went in with a shoulder injury and Alex was exceptional at walking me through a strengthening program to get to where I wanted to be. Will be back for all physio needs.

Had 9 months of physiotherapy with Giacomo Silvestri. I was very impressed with him. He's knowledgeable, patient, and his treatments were effective. He's also nice. Very professional!

Love Cornerstone Physio! My PT, Ala, has helped me with a shoulder and hip injury. She is very knowledgeable, encouraging and helps you achieve all your goals. I would highly recommend this clinic to anyone looking for a physiotherapist.

Cornerstone came recommended by my physio in Vancouver, so I was surprised to find that the receptionist who took my call was not particularly friendly or helpful. She was unable to provide information about differences between virtual and in-person assessments and did not offer to find out for me. This is not necessarily a reflection of the skills at Cornerstone, but she was the first point of contact and makes me unlikely to want to inquire further.

Edit (after response from owner) : I appreciate the response and willingness to rectify the situation, so I have changed my review to 3 stars, but am not interested in further contact at this time. Thank you.

I met Alex Restrepo at Cornerstone team, in January 2021. When I met him, my back pain had considerably limited my life style. Alex listened to my story, asked critical questions to find the root of my pain and helped me understand not ony what was happening but how we could improve and solve the issue. Alex is a superb professional, knowledgeable, friendly, supporting and encouraging. He provided me with guidance, advice and, above all, tools to bring me back to a pain-free life. And he delivered! I am now pain free and I know how to maintain my actual situation. You will have to do the work, but with Alex's guidance and help it will pay off. I totally recommend Alex and Cornerstone!

With a severe injury to my right rotator cuff, I found my way to Cornerstone. I am fortunate to have been teamed with a physiotherapist who is very professional and a team player. Alex always treats me as a partner in my treatment and is open to hearing my thoughts about my own progress. The front office staff is warm and friendly and efficient. I believe the entire staff reflects the values of the company. I would recommend this team to anyone in need.

Overall, I had a very positive experience. Cornerstone is a professional, tidy place, and gave me the best treatment I have received for my TMJ issues. Highly recommend Giacomo - the treatment was not invasive and ended up helping me a lot with my jaw pain and clicking. He is also very patient and trustworthy. If you have any issues, this is definitely the place to go! The staff are very kind, educated and willing to help. Big thanks to their amazing team!

We had an excellent experience dealing with knee pain. Highly recommend! Giacomo was very helpful and knowledgeable!

I can't say enough good things about this clinic, especially during COVID. From treating sports or other injuries, I have felt well supported by excellent physios to make a plan for return to play. Most recently Alex made sure I could getting running again and Jocelyn fitted me for new orthotics that are making a good difference. The clinic is super clean, preventative measures are in place and the staff super helpful.

I highly recommend Cornerstone. I first saw Giacomo Silvestri for a bout of persistent BPV (vertigo) and I was so impressed with his approach to diagnosis and treatment that I asked him if he could help me with some longstanding back pain issues. I had consulted a few physios about this over the years, but Giacomo's methodical approach and clear communication, working through various stages of the problem have given me the best results, and now although I still have some pain, I have the tools to manage it on my own.

I had a bad frozen shoulder and subsequent neck pain, and Jocelyn worked on me diligently until I was pain-free. Her professionalism and pleasant demeanour made my visits a pleasure. I would highly recommend Cornerstone Physiotherapy.

I had an acute back injury a few months ago. My physiotherapist Alex was super timely and helpful. Alex was very patient with me and was really good at explaining my exercises. Because of Covid restrictions, our sessions were online. Despite that, I received amazing care and walked away with tools to help me with injury prevention in the future. The booking and payment structures were easy to use, and the staff were friendly. I would highly recommend!

Three times in the last decade I've been referred to Cornerstone for help - first with knees, then a hip, then a shoulder - and three times I've emerged a few weeks later with a pain-free fully-functioning body. And what's more, with the tools to keep the problem from recurring! They're terrific!

Ala Hojjati, like the therapists I'd met previously, was not only deeply and effectively in touch with the mysteries of the human body, but also a delightful person to work with and learn from. Bonus! I'm deeply grateful for what she gave me. Thanks, Ala!

Hayley was amazing in helping me recover from a double MCL injury. I was able to get back to my routine quickly with her guidance and targeted exercises.

Mara is so nice and professional as a receptionist, as she can always response my email within 10 mins or less, and she kindly offered everything I needed for the upcoming sessions. Also, I definitely recommend my physiotherapist Ala, she is very nice and provided me with proper massage and exercises in and out of the session. I used to have numb left calf and pain back, but after a few sessions, I feel much better as she identified my problem and gave me clear instructions from how to release the pressure of my back to how to make the back muscle stronger step by step. I really appreciate her help along the way. I will definitely recommend Cornerstone!

I had a wonderful experience with cornerstone. HAILEY did a full assessment and quickly found the cause of the pain. In about 5-6 sessions the pain subsided. Hailey is a great listener and super knowledgeable

My experience with Giacomo, my physiotherapist was excellent. My husband Michael also went to him and said he was fantastic.
Giacomo was very professional and engaging. Always remembered details between visits. He is well educated in his field and answered all my questions. I would highly recommend him to anyone.
The office staff at the front desk were always courteous and sent out reminders of our appointments.
I would give this clinic 5 stars.

The team at Cornerstone are great. Alex at the Carlton St.location helped me recover from 2 sprained ankles (yes, it was hard to sprain both). He started me off with some excercises that I could do at home, and layered on more strenuous excercises over several weeks. It was lots of work, but Alex was always encouraging. I would definitely recommend Cornerstone!

I had an amazing experience with Cornerstone Physiotherapy Сlinic! Only after 4 visits to Alex my lower back pain that was lasting almost a year disappeared! I would definitely recommend them!

Excellent service both in person and virtually. My physiotherapist was fantastic and her work got me back to being pain free!

Giacomo Silvestre was excellent therapist. Good followup. Helpful email with illustrations of exercises. Would have given 5 stars but reception area etc could use some updates.

Giacomo was a great physiotherapist, very knowledgeable and professional. Had a great experience, felt significant improvements in my body. Highly recommend.

This clinic is highly recommended. I had sever postpartum knee and back pain when I started physio with Alex.

He is very knowledgeable and professional. I had an assessment first and he explained clearly what is the problem with my knee and back. I started with very simple yet effective exercises and kept practicing everyday. After 3 months I was fully recovered and was able to be back to my normal life style.

Thank you again Alex. You are the best.

I strongly recommend Cornerstone to anyone looking for effective, evidence-based physiotherapy. I see Alex, who helped me end years of Achilles tendinitis and is now treating my knee pain (much improved). He clearly explains the cause of the problem and how the treatment will resolve it. I’m also impressed by the clinic’s strict safety protocols (health checks, masks, sanitizing between visits).

I highly recommend Alex Restropo. I had been suffering from lower back pain for at least a year and a half, and had been to other physiotherapy practices with no results. I'd almost given up, but Alex was able to bring me back to full function! Kudos as well to the office for maintaining strict protocols around COVID.

I’ve been coming to Cornerstone for many years and have been treated by 3 different PT. I’ve had great service and I highly recommend them. I highly recommend my current Physio Therapist (Ala Hojjati). She’s very knowledgeable, professional, and has a great ‘bed-side’ manner! The office staff are always pleasant and professional. IH

I required physiotherapy following a recent shoulder dislocation. Overall my experience at Cornerstone physiotherapy was excellent. The staff are organized, professional and accommodating. My physiotherapist (Jocelyn) is knowledgeable and provided a thorough recovery program.

I first discovered Cornerstone years ago following a back injury. After shopping around at other physiotherapy clinics, it became clear that Cornerstone outperformed all other clinics.

One obvious caveat is accessibility. It may be a challenge/stressor if you are coming by car.

Ala took care of my knee and gave me many exercises to work through. Helpful and caring. I have seen two other physiotherapists at Cornerstone over the last 8 years and am always happy with the attention, knowledgable advice and treatment I get. Excellent.

I received in-person and virtual physio treatments from Alex Restrepo, who has helped me SIGNIFICANTLY improve the symptoms of a chronic shoulder injury from years of sports.

Alex is detailed and thorough. It was helpful that throughout the treatment he made it a point to also teach me and help me understand what my body was going through. This new perspective really made physio more enjoyable this time than in the past.

After being consistent with seeing him and doing my prescribed homework for a couple of months, I was 95% better and felt in control of my shoulder for the first time in a while.

I’ve had countless experiences with other Physiotherapists, but Alex’s demeanour and expertise certainly stood out to me. I highly recommend his services!

I was experiencing severe vertigo and dizziness. My doctor suggested I go to Cornerstone Physio for help. I saw Giacomo who narrowed down the possible diagnostic options and began treating me for vestibular neuritis based on my symptoms. I had never heard of it and was thankful there was such a thing as vestibular rehabilitation. I have made huge progress with therapy. I’m impressed with Giacomo’s knowledge and his passion. I appreciate the motivational push when I needed it. The staff are courteous and professional and made my visits very comfortable. I highly recommend this clinic. Nancy

I have been attending Cornerstone Physiotherapy on College St and have found their operation to be thoroughly professional. The reception staff does a great job of handling both appointment bookings, and have a great understanding of the various insurance coverages people have and processing claims on their behalf. They are very pleasant as well as helpfulto deal with, so your first impressions of Cornerstone is very positve.

I worked with Alex R, one of their physiotherapists for a couple of injuries that I had (neck and then shoulder issues). He did a great job of designing a series exercises to safely re-hab my injuries and added variations and additional exercises as I progressed. He took the time to explain what the causes were of the pain and why he was advising particular exercises to alleviate the discomfort and lack of mobility. His manner is very professional, and at the same time he understands the pain that you are going through and has a very friendly, supportive demeanor that is encouraging during the recovery process.

Alex was able to get me healed to the point where I no longer require appointments with him, but should I need assistance for any other injuries in the future, I would certainly go back to Alex and Cornerstone.

Professional and friendly service that was instrumental in getting my body to be able to run again! I highly recommend Cornerstone!

I was comfortable and pleased with Giacomo and Cornerstone Physiotherapy over my appointments this year for a temporary injury. My physiotherapist was knowledgeable, explained my treatment plan and addressed my questions and concerns. I was also comfortable with the building, office and physiotherapist's thorough COVID-19 safety protocols. Although I hope to avoid future injuries, I would be very comfortable returning here if needed.

Went for physio sessions during COVID-19 and everyone was masked and distanced so I felt quite safe! Alex was such a huge help with my back pain. He patiently explained exactly what was going on with my spine. With his recommendations, I'm now back to 100%!

Friendly, knowledgable, effective, and honest. Focused on recovery, no pressure for perpetual appointments. Highly recommended.

Giacomo is an amazing physiotherapist. Professional, highly competent, exceptionally warm and caring and gives you just the right push to keep you focused on your goal. I highly recommend Giacomo and this Clinic. Everyone is nice and friendly at the reception.

Excellent experience working with Alex. I had suffered from a serious ankle injury in the summer and Alex was able to guide me and help me recover in the best way possible. He not only focused on recovery, but he also focused on what activities I would do after my recovery (mainly soccer and HIIT training) and tailored my exercises accordingly. Very happy with the experience. They also took all the necessary precautions and protocols to enable a safe experience amidst this pandemic so I was never worried about potentially contracting the virus
