Dr. Granfone is awesome. He takes the time to listen, to explain, and to make sure that I'm comfortable with his decision and with his suggestions.

Dr Granfone is the best doctor I have ever consulted with. He genuinely cares about my health and well-being, carefully listens to my concerns, and candidly discusses the reasoning behind his decisions and advice. I travel two hours from home to MGB to see him because I value his advice that much.
