Dr. Sewall is an amazing cardiologist. I trust him with my heart health care in every situation. He is compassionate, a terrific listener, and extremely accurate in explaining and recording all of my test results. Dr. Sewall has an outstanding staff that surrounds and supports him and his patients. Results of testing come back quickly, and are explained in great depth. My wife, brother, and mother-in-law are all patients of Dr. Sewall. I always leave my office appointments more confident than when I first go in.
