Dr. Rajanahally is the best! He is my cardiologist and my sister's cardiologist. He saved her when she had a heart attack and still takes care of her, her heart needs, and has kept her healthy and strong for over 10 years. Heart disease runs in our family. 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. Recommend him, YES!
