Dr. Sun is one of the, if not the most conscientious and caring physician we have known. My wife and I have had extensive experience in the medical field and we do not offer this kind of commentary lightly. He clearly evidences his concern by spending as much time with you in consultation as you need, he follows up on expressed concerns, and his offers his care in a non-judgmental way that clearly genuinely communicates his interest in seeing your overall improvement in health. We are glad we happened to land on him as our cardiologist.
