I seen Dr Stephan as recommended by my retiring cardiologist. I couldn't be happier upon our first meeting. He is very approachable. He listens & hears what you say. One of the things about him, that stands out to me, is that he seems like a "down to earth" type of person, which I so appreciate. I'm going to keep him. :)
