I have psoriatic arthritis as well as rheumatoid arthritis. Walking was getting tougher and even times of rest were painful. I wanted the best treatment by the most knowledgeable and experienced people. I met with Dr. Haas and staff and was very impressed. At the time, I worked at a large medical center. The process at HSS was so incredibly well thought out and simplistic-from pre-surgical testing to day of surgery to my hospital stay and post-op visits - incredibly wonderful. Everyone from housekeeping to MD’s is an active part. I know from being on the working end of a hospital - these folks do it very well. I sing their praises every time someone asks for a referral. The reputation of HSS is well deserved.
