During a medical mission to Peru, Dr. Neil Donohue discovered how he wanted to spend his life. He had traveled to the foothills of the Andes to treat people suffering from foot diseases and deformities, and came face to face with countless cases of people crippled by clubfoot and ravaged by disease. This experience moved Dr. Donohue so profoundly he launched a worldwide campaign to end these types of afflictions in 1997 by forming The World Walk Foundation. In this episode of The Visionaries, we follow Dr. Donohue as he travels the globe treating people who have been struck down by illness or misfortune. Our story starts in Philadelphia, home of the World Walk Foundation, where Dr. Donohue provides diabetes education and care to the underserved in the inner city. We then travel to rural Venezuela with the World Walk team of physicians and witness as they perform life altering surgeries to those who may never have the opportunity to be helped again. This is an emotional story of how one man's vision to help others has grown and inspired others to join him on a truly noble crusade.
