The American Himalayan Foundation (AHF) is a non-profit organization in the United States that helps Tibetans, Sherpas, and Nepalis living throughout the Himalayas. AHF builds schools, plants trees, trains doctors, funds hospitals, takes care of children and the elderly, and restores sacred sites. The San Francisco-based organization also helps Tibetans rebuild and maintain their culture both in exile and inside Tibet. It was founded by Richard C. Blum. The late Sir Edmund Hillary was a Director of the foundation for more than 20 years.
