In 1994, a group of Zamboanga-based doctors entered into a consortium with the Ateneo de Zamboanga under Fr. Kreutz's presidency to establish a medical school named Zamboanga Medical School Foundation (ZMSF). It was located on the La Purisima campus. In 2004, ZMSF was turned over to Ateneo. The medical school became the Ateneo de Zamboanga University School of Medicine. Partnering with the universities of Calgary, Laos, Nepal, and Cambodia, the School of Medicine uses problem-based learning and community-based approach to medical practice with emphasis on serving communities in Western Mindanao.
