Family physicians complete an undergraduate degree, medical school, and three more years of specialized medical residency training in family medicine. Their residency training includes rotations in internal medicine, pediatrics, obstetrics-gynecology, psychiatry, surgery, emergency medicine, and geriatrics, in addition to electives in a wide range of other disciplines. Residents also must provide care for a panel of continuity patients in an outpatient "model practice" for the entire period of residency. The specialty focuses on treating the whole person, acknowledging the effects of all outside influences, through all stages of life. Family physicians will see anyone with any problem, but are experts in common problems. Many family physicians deliver babies in addition to taking care of patients of all ages.
