I was a patient of my previous cardiologist for over three decades. When he retired I searched for someone who would be as kind, caring and knowledgeable. After working with two cardiologists I happened upon Dr. Mezzafonte. He has been a God Send for me. He answers questions promptly and thoroughly via the patient portal or by phone at the end of his. work day. I am not an easy patient. I don't know where he gets his patience; but I'm glad he has it because he needs it with me!!
