A large faculty of behaviorists are drawn upon to teach family medicine residents in areas which range from substance abuse and adolescent medicine to family counseling and independent living for the aged and for those with chronic mental illness.

Institutional Faculty

All coordinators provide consultants from their respective specialties and appropriate subspecialties to provide round-the-clock back-up for the Family Medicine Service, as well as consultants for specialty clinics, didactic conferences, and special workshops and other learning experiences.

Coordinator of Adult Medicine Training

Juan Barrio, M.D., Director of Internal Medicine Residency Program, coordinating with the Family Medicine Director of Inpatient Training, ensures rigorous medical subspecialty educational experience with case selection appropriate for family medicine training.
