During a recent visit to the USA, I was in need of physio due to a back issue. Onyx and Steve McFetridge recommended to me. Couldn’t have been better taken care, this kind friendly and very professional young man soon had me feeling real good real fast. Cannot recommend highly enough…Thank You Steven

I wish I had met Steven years ago. I am a former track and cross-country runner who has done various sports over the years including running, soccer and basketball. In my mid-60s now, I have been frustrated for a few years with a variety of issues in my feet, knees, hips, and back making me feel weak and imbalanced at times. I have tried various things including going to orthopedic and chiropractic doctors. Steven is the real deal. I would highly recommend him to any athlete at any level as well as everyday people wanting a more sustainable platform for long-term health. I was in a negative loop of having various muscle imbalances, too much sedentary lifestyle, and growing lack of confidence in my body for everyday activities and exercising. Steven has a comprehensive and customized approach, including expertise with dry needling. He quickly diagnosed my core issues and has had me on a step-by-step plan with a variety of exact exercises that are building back my strength and mobility in key areas. I am achieving my goal of having a sustainable health and fitness regime for the long term. I have always been a pretty self-aware person in terms of mind, body, spirit connections, experimenting successfully with meditation, tai chi, grounding, chi-running and more. However, I was at a low point recently and realized I needed expert help. I wished I had discovered the benefits of physical therapy in general, and found Steven in particular, much sooner. He has the right combination of know-how and why, different type of interventions, coaching, and training to really make a difference. I could not do it on my own. I needed the exact approaches Steven is helping me with to support, guide, and push me forward.

I’ve been seeing Steven at Onyx Physio and Performance since November 2025 and can’t recommend him enough. He is extremely professional, truly listens to what’s going on, and never makes you feel rushed during your appointment. I’ve had dry needling for years, and the treatment Steven provides has made a tremendous difference in my recovery and overall wellness. Highly recommend Onyx for PT and dry needling if you’re in need of quality care!

I came in with an achilles tendon issue and finished physical therapy pain-free. Steven gave me the tools to manage and fix my pain, and used dry needling to help relax the muscles. He was incredibly helpful and very knowledgeable.

I’ve been in pain for a long time, and after just a few sessions with Steven, I feel amazing. He’s knowledgeable, attentive, and explains what’s going on in a way that actually makes sense. For the first time in a while, I feel hopeful and excited about regaining my strength and mobility. I’m genuinely grateful for the progress I’ve already made and looking forward to continuing treatment with him.

I’ve been seeing Steven throughout my marathon training, and he’s been amazing. He carefully assesses my progress each week, adjusts workouts when needed, and gives targeted exercises that have genuinely reduced and managed my pain. I’m feeling better and finally able to train confidently again. Highly recommend!

I had an incredible experience at Onyx Physio and Performance. Dr. McFetridge is a phenomenal, knowledgeable, compassionate, and genuinely caring professional with a great bedside manner. He provides truly 1-on-1 care, always taking the time to listen and explain complex treatment plans in terms that are easy to understand, making the approach feel completely tailored and sensible. He uses advanced techniques to get to the root cause of my pain and restore my full function. If you need lasting results from a therapist who listens and communicates clearly, I highly recommend Dr. McFetridge!

I am so thankful that I found physical therapist Dr. Steven McFetridge – he is amazing! Not only is he exceptionally knowledgeable, he is remarkable at translating recommendations into individualized care. I am a person who loves to know the “why,” so I appreciate that with each appointment, he explains what he is doing during the assessment and the rationale for selected exercises. As a doctor of PT, Steven also incorporates manual adjustments (joint manipulation) and is certified in a number of treatment modalities such as dry needling. And equally as important, Steven is incredibly kind and compassionate, putting you at ease instantly! If you are in physical pain and contemplating (or even fretting over) next steps for relief, I would encourage you to reach out and make an appointment with Dr. Steven McFetridge!
