John F. Beshai, MD, FACC, FHRS

Dr. Beshai is internationally renowned and respected. He has been invited all over the world to lecture and speak on his areas of expertise and research. He has published his research in all the major journals including The New England Journal of Medicine, Journal of American College of Cardiology, Heart Rhythm, American Heart Journal, and the American Journal of Cardiology. His most notable attribute, however, is his ability to connect and communicate with people.

As a teacher, he understands that every training level has very different degrees of fundamental knowledge and understanding from the most basic medical student to the most advanced training level of cardiac electrophysiology fellow. The ability to understand these differences and tailor education based on the degree of training translates to the ability to naturally connect with patients on their level.

Collectively these attributes have created a name that patients seek directly and that referring physicians trust with their patients. Upon meeting Dr. Beshai, patients feel an instant connection and level of confidence that puts them at ease.
