Klaus-Dieter John (1960-) dreamed of becoming a medical missionary in the developing world. He would do whatever it took -- study in top universities and practice surgery in remote and dangerous places -- to reach his goal of providing health care for people who needed it most. Dr. John's seemingly impossible vision of Diospi-Suyana, a world-class hospital for impoverished Peruvians deep in the Andes Mountains, was blessed by God to the end. Despite challenges in fund-raising, construction, moving his family from Germany, and countless roadblocks, Klaus's dream was finally realized, bringing hope in a land loved by God.
