After my very painful Shoulder Rotary Cuff Surgery I was in therapy. My Physical therapist Gary is the best in his field. He is patient and kind but yet assertive as needed. I would recommend him to anyone 100 times over and over. I have still yet to finish my therapy but Gary will get me there... more

Helped me through post-surgery PT. Helpful, responsive and adaptive to my needs. Support staff is great and the environment is clean. Would recommend friends, family and random folks off the street in need of PT.

Gary has been treating my son Trevor since he was a teenager. His professionalism is outstanding and his care for his patients is awesome!!! I wouldn’t have my son be under anyone else’s care except Gary’s!!! He’s the absolute best 😊
The therapists are knowledgeable, caring and patient. They educate you on what you have to work on, how and why. I was fearful going in but completly trust their judgment and how far i can push myself. They genuinely care about your well being. Thank you .

Great staff and they work with you to push you far enough to see results without it being torturous. Very flexible scheduling and just great overall.
