Dr. Mark Willett is originally from the Philadelphia area. He did his undergraduate studies at Cornell University in upstate New York, but moved out to California to go to graduate school at UC Davis, studying ecology. He earned his Master's in Ecology at Davis, doing fieldwork in the rainforests of the remote South Pacific nation of Papua New Guinea.
Dr. Willett went on to go to veterinary school at Davis, graduating in 1997, with an interest in zoo and wildlife medicine. After vet school, he became involved with a project to save the endangered Channel Island fox, a small fox that is found only on islands off the coast of Southern California. He is very happy to say that the foxes are doing well, and are slated to be removed from the Endangered Species list. Most of Dr. Willett's time is now spent doing small animal medicine, though he still consults with the fox project. He also has an interest in exotic animal medicine, treating rats, snakes and rabbits.
