- Chris P.

I have worked closely with Adam and Ryan for the past 5 years. I am a personal trainer in Back Bay Boston. Anytime I need to refer my clients out for pain, they are my go to Physical Therapists! They are able to isolate and diagnose the problem quicker than I. The communication is what I love best about them. They provide the client and I with the tools and resources that we need to help them succeed. They truly make it a team effort to helping others get back to there true athletic potential.

- Emily I.


I’ve been working with Kyle for only 3 months, however, my training experience has been by far the best one I’ve had in 20+ yrs. of working with personal trainers. Ryan, Adam and Kyle are physical therapists by training, which I believe is an invaluable asset in understanding the individual needs, limitations and goals of their clients. I appreciate the positive and motivating approach and would highly recommend working with them!
