Jennifer File, DO
Dr. File grew up as an Army brat, moving every few years to locations all over the country. Because she moved so much and spent a quarter of her childhood in Germany, she developed a love for learning about different cultures and languages. In college, she majored in German and minored in Spanish. Soon after college, she served two years as a Peace Corps volunteer in the small village of Hort, Hungary, as a primary school teacher. During her second year, she volunteered monthly at a Bosnian refugee camp. When she arrived in the U.S., she started her premedical studies while working in various positions with Physicians for Human Rights, most notably as the liaison officer for the Bosnia Project. She then completed medical school at Touro University College of Osteopathic Medicine in Vallejo, Calif.
When not in the office, you might find her on the beach with her dog, snowboarding, going for a run or doing a little yoga. Read more about Dr. File.
