Gorilla Doctors is dedicated to conserving wild mountain and eastern lowland (or Grauer's) gorillas through life-saving veterinary medicine and a One Health approach. Gorilla Doctors’ international team of veterinarians is the only group providing these critically endangered animals with direct, hands-on care in the wild. Gorilla Doctors operates in the three countries where mountain and Grauer’s gorillas live: Rwanda, Uganda, and the Democratic Republic of Congo. The program is the realization of a dream of legendary American gorilla researcher Dian Fossey, who dedicated her life to studying and protecting mountain gorillas in Rwanda’s Volcanoes National Park. The donor-funded program is a partnership between the Karen C. Drayer Wildlife Health Center and the Mountain Gorilla Veterinary Project.
