Testimonials

What our customers say

I’m 58 years of age and I’ve always had a “delicate” and painful back. I felt achey most of the time. Dr. Ratiner and his office have correctly diagnosed my problems, which can now be helpful. His office is kind caring, and efficient.
He also has a wonderful physical therapy department that has made it easier for me to deal with my pain and stiffness. It is a pleasure for me to thank Dr. Ratiner and all his staff.

Patient

I have been a patient of yours for some years now and I just wanted to let you know how caring and great your Physical Therapy Department is. Everyone is so kind and gentle. You know the problems I have in my hands with Osteoarthritis. The therapist started doing therapy on my hands and what a deep tissue massage he gave me. I understand that he has been doing this for 20 years and also taught classes. He also does some Chinese techniques that when I left your office I could not believe how great my hands felt. I heard he is a master at this and I believe it.
Dr. Ratiner, like you your Physical Therapy Department is great. Thanks for being such a caring doctor. You listen and really care so much about how your patients are doing.
