About Stewart G Allen

About The Provider

Dr. Stewart Allen brings considerable training and expertise in general and interventional cardiology. He was trained at Wake Forest University in Winston-Salem, North Carolina and completed fellowships in clinical cardiology, cardiovascular research and interventional cardiology.

Dr. Allen’s expertise includes advanced coronary interventions, peripheral artery interventions, transcatheter aortic valve replacement and pacemaker placement.

    I really like Dr. Allen since he is very patient with me. Dr. Allen speaks in layman English so that I can understand what are my late husband and my health concerns. He never acts like "your time is up!", and I have been known to ask him a million questions!
