Dr. Einhorn is the one of the best physician’s I have ever seen. He is always friendly, kind, considerate, and most importantly knowledgeable and caring. He strives to provide his patients with the best most up to date cardiac care. I always highly recommend him to my family and friends. He was actually recommended to me by a physician who is a patient of his. To me that speaks volumes.
