About the Founder

Dr Harper

Dr. Will Harper has twenty years of experience as an internal medicine physician in Chicago. Named to Top Doctor lists in the region, he is focused on delivering high quality internal medicine in a way that patients feel valued and truly cared for.

Prior to founding Harper Health he held a number of different roles as a physician-leader, including directing a number of core medical school courses at the University of Chicago Pritzker School of Medicine. He created curricula that taught rising physicians the art of being a doctor: that unique blend of communication skills, physical examination and clinical reasoning. His success led to senior positions with national medical education associations, including the Society for General Internal Medicine and the Association of American Medical Colleges.

From co-founding and running a successful wellness coaching business for six years, Engaged Health Solutions, to acting as the medical director of the executive physical practice at the University of Chicago Medicine for more than fifteen years, to serving as lead internal medicine physician for the Chicago Blackhawks for ten years, Dr. Harper’s mission in medicine has led him to where he is today: founding a clinical practice that best meets the needs of patients, physicians and the team that supports them.
