David Sabgir, MD, is a board-certified cardiologist practicing at Mount Carmel Medical Group in Columbus, Ohio. Frustrated at his inability to move the needle on his patient's self-care, he had the idea to just invite them to go on a walk with him. This modest idea eventually blossomed into Walk with a Doc, a movement within the field of lifestyle medicine whose mission is to empower doctors to share the health and happiness benefits of walking with their patients.
