From the moment I walked in the ONS door with my broken right patella, I knew I was in the right place! I was most fortunate to be referred to Dr. Vadasdi by two of her former patients. I immediately felt comfortable as she is an Ironwoman Triathlete and I am a 3 time Ironman.
The entire ONS group, from surgery to PT, has turned a most difficult situation into a pleasant one. I am always greeted with a warm smile and never wait more than five minutes. The staff at ONS took care of ALL my health insurance needs leaving me with my sole responsibility of showing up on time. I would highly recommend ONS to anyone in need of orthopedic care or PT. They are simply the best. This is from the heart as I am soooo grateful for ONS taking good care of me!! (patient S.W.)
