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. :)

Dr Stephan is terrific. Explained clearly outcome of heart scan test taken last year. Very logical next steps to validate and confirm current condition. First appointment with him and totally impressed with his professionalism and approach. Well done.
