My experience with Dr. Chalmers and his assistant Dustin were first-class from start to finish. I was diagnosed with bone-on-bone hip arthritis in April and immediately scheduled for surgery in May for a total hip replacement at the HSS Main Campus in New York City. The surgery was very successful. I stayed one night in the hospital, which was very helpful. I began PT immediately at home for five sessions and continued at HSS Westchester. The entire time I was followed by Dr. Chalmers who was always available to me. I can’t say enough about how positive an experience I had with Dr. Chalmers and HSS.
