Dr. Delos – When my arthritis got so bad that I couldn’t walk, I knew I needed to have my right knee replaced. I went to ONS because my daughter had been treated by Dr. Camel and Dr. Sahler, and I was very impressed by how supportive and caring they were. As soon as I met Dr. Delos, I had every confidence that I was in good hands. He has a great bedside manner, he’s honest and straightforward. He took the time to answer every questions my husband and I had about the procedure. Two months after my surgery, I was able to take a trip to Cancun and walk around the Mayan ruins and the only thing that bothered me was the heat. I’m going to Disney World next month, and I can’t thank Dr. Delos for making it all possible. I recommend ONS to everyone. Sandra S., Pelham, NY
