Patient Reviews

  • "New York Cancer & Blood Specialists is by far the best medical organization that I've ever experienced. All the care providers have been at their best. This includes Dr. Diamond, Dr. Harris, Christine P. NP, and Stephanie. There are many more, although I don't recall their names. I've been to the Greenlawn location and now since the move, the Smithtown location. Thank you so much to all the people who took care of me."
