He cares about his patients and keeping them healthy. I've had several test like stress test, EKGs, bloodwork on a regular basis, etc. when I've also had issues or concerns. Always monitoring my health and heart. He's an excellent cardiologist. Like me and my sister, anyone I've met or know him have nothing but praise for his abilities and care. He is kind, very skilled and knowledgeable. He takes the time to throughly go over any test results, conditions you might be experiencing, exams you, explains your health needs, listens and answer any questions I might have.
