Love Dr. Greenstein....very concerned and caring. Called to tell me my test results were not back yet and then called again when they came back. I think hes excellent.

Dr. Greenstein came highly recommended from another doctor as one of the best arthritis doctors in upstate NY after I left the practice of a sadistic monster in solo practice in Albany. I am so glad I changed! Dr. Greenstein takes plenty of time to listen and explain things in laymans terms. He is gentle and compassionate, and has a very human and down-to-earth essence about him. He is always friendly with a warm sense of humor. I dont ever intend on changing doctors even if I move out of state. Ill come back for my check-ups just to stay with him.

Dr. Greenstein is no longer practicing but I just wanted to say he was my doctor for over 25 yrs and I love him! And I miss him.

Dr. Greenstein is an amazing doctor who really helped.

I went to him because my rheumatologist retired. A year and a half ago I was diagnosed with rheumatoid arthritis and put on 2 medications. When I went to Dr. Greenstien he told me that I didn’t have arthritis, no one in the office would think so, and that I probably had fibromyalgia. He then told me to go read a book about it and stop my medication, and if a few months down the line if I was in pain and agony I could come back and receive treatment from him.
