Notre Dame alumnus Dr. John May ND '84 switched his major from engineering to preprofessional studies when he was inspired by the story of physician-humanitarian Dr. Tom Dooley. Later, he earned an M.D. at Loyola-Stritch School of Medicine in Chicago, and dedicated his career to providing medical care in jails and prisons, both in the United States and around the world. He founded Healing through Walls in 2001 in Haiti, where the organization now has 50 medical professional employees working in prisons. Healing through Walls also operates in the Dominican Republic, Jamaica, Malawi and the Congo and consults across the Caribbean and Africa.
