Last year he replaced both my knees and from the diagnosis through the recovery period i cannot provide enough praise for him and his staff. They dealt with complicated insurance issues and fought to get as much coverage as possible. Once approved for surgery the experience with HSS was first class. I would not go or send my family anywhere else for orthopedic matters. You are good hands with Dr. MacGillivray and HSS.
