We believe the world would be a better place if healthcare were more broadly distributed. Our story begins with our founder Dr. Glenn W. Geelhoed, who has taken medical mission trips to points all over the globe for more than forty years. Inspired by his legacy, Mission to Heal provides surgery and surgical training to some of the most destitute people of the world in some of the most desolate places on the planet.



Glenn received his BS and AB cum laude from Calvin College and MD cum laude from the University of Michigan. He completed his surgical internship and residency through Harvard University at Peter Bent Brigham Hospital and Boston Children’s Hospital Medical Center. To assist in developing further volunteer surgical services in underserved areas of the developing world, Glenn completed masters degrees in international affairs, epidemiology, health promotion and disease prevention, anthropology, and a philosophy degree in human sciences.

He still works as a professor of surgery at George Washington University Medical Center in Washington D.C. and is a member of numerous medical, surgical, and international academic societies. Glenn is an avid game hunter and runner. He has completed more than 135 marathons across the globe. He is also a widely published author accredited with several books and more than 500 published journal articles and chapters in books. He has two sons and five grandchildren.
