Meet Your Therapist


James Kalenderian, PT
President, SoundSide Physical Therapy

Graduated from the University at Buffalo in 1999
Degrees in Physical Therapy and Sport & Exercise Physiology

When I became a physical therapist my goal was to provide outstanding one-on-one care.  Not satisfied with the quality of care that was available, I decided to venture out on my own.  I began small, visiting homes of my patients to provide the excellent one-on-one service that I believe in.  The overwhelming response I received from my home care services led me to open my first clinic in September 2001.

It has been a pleasure being part of the local community which has enabled us to relocate my practice nine years later to a much larger state-of-the-art medical complex located in the heart of Locust Valley.  The goal of my outpatient orthopedic facility is to continue the intense one-on-one attention while offering the best environment for rehabilitation.  I have invested in new state-of-the-art equipment, including the Biodex un-weighting system and a line of Quantum & Sci-Fit exercise equipment. 

As always, my primary goal when treating patients is to provide quality one-on-one physical therapy allowing our patients to progress with rehab in the most timely and efficient manner possible.  SoundSide stands for quality care with a personal touch.
