Dr GRANFONE was extremely kind and patient. I was seeing him for a second opinion. He reviewed all my symptoms and past studies. He went through all the possibilities and why they could or couldn't work with my symptoms and studies. He listened carefully and was very caring and understanding. He did not diminish my concerns which was reassuring. He explained everything in easy to understand terms. I would highly recommend him to others and return if needed.

Dr Granfone was well prepared in advance for my visit (read my chart, history, etc). He asked excellent questions and explained things well. He followed up in ordering tests. He was very easy to talk with. I had confidence in him.

Dr. Granfone is the kindest, most respectful and thorough Dr. I have ever seen, honestly. He explained everything better to me than any other Dr. I've seen about this issue. He listened carefully to everything I said and asked. There was no reason for any follow up appointments, but he had wanted to reach out to another specialist with some questions. He did, and has called me three times since I left there to give me further information. Too bad he doesn't live in Maine and isn't a general practitioner, he would be a great PCP that I would gladly go to!
