Mark Hart, MD


Main Profile

Dr. Hart specializes in diagnostic and interventional peripheral vascular disease. He worked as a paramedic firefighter before going to college. This (and his last name) influenced his decision to pursue a career in medicine.

The challenge and variety of cardiology drew Dr. Hart to this specialty. He says his favorite part of cardiology is developing long-term relationships with patients and helping them improve the length and quality of their lives over time.

In his spare time, Dr. Hart loves working with horses. His equestrian interests led him to serve as a physician for the US Olympic team.
