Patient Testimonials

Thank you, Dr. Martin, for believing my pain and looking for deeper reasons. Now I know there is something to keep an eye out for. I’m grateful you think physical therapy is a good treatment plan because this has been tremendously helpful and eye opening. As a reasonably young and healthy women, I did not realize there were several issues with my strength, but especially stability. PT has given me additional teammates, friends, and family through this journey towards normalcy. Knowledge and acceptance of the lurking invisible illness, slowly but surely. Thank you!
