This week’s episode features an inspiring guest: Dr. Klaus-Dieter John—a world-renowned surgeon, medical missionary, and founder of Diospi Suyana, a modern hospital serving the Quechua people in the Peruvian Andes. For nearly 20 years, Dr. John and his wife, Dr. Martina John, have faced incredible challenges while bringing high-quality medical care and the hope of the gospel to thousands who previously had little to no access to healthcare.
