“I had the best post op instructions and follow up care I’ve ever had & ONS Physical Therapy was brilliant. I feel very fortunate to have been under his care and have made a full recovery. My knee feels awesome! I’m very grateful to Dr. Kowalsky, his team and my PT Bethany Deer for all of their help and most of all for truly caring about my recovery. THANK YOU!!” – 5 Star Review on Healthgrades
