Doctor Johnson and his staff are excellent. He is fully up to date on all of my medical history from all sources when he enters the room. He listens and considers all inputs from me. I value his opinions and advice and believe there are no better qualified doctors. I left a practice in NJ when I moved here I struggled to find a cardiologist I trusted here in DE. Dr. Johnson is who I can trust to make good decisions for me. I trust my life on his judgments.

Dr. Johnson was amazing! My first visit, and he had read all the information electronically sent over, and discussed much of it at length with us. He's an old-fashioned doctor with a holistic outlook and marvelous bedside manners!
