  • "Nothing but excellence and true care from Dr. Diamond and the staff at New York Cancer and blood specialists located in the Smithtown office.Though my issue was a small problem, I was treated with respect and care every time I walked through the door. The Doctor was able to work through my mind boggling medical issues being addressed outside of his realm and focus on the issue he was requested to deal with, which they handled with zero problems. I highly recommend these folks."
