This paper describes development, implementation, and evaluation strategies of a longitudinal geriatric curriculum, the Senior Mentor Program (SMP). The rationale for exposing undergraduate medical students to healthy, community-dwelling older adults is to use the relationship and activities as vehicles for improving knowledge of aging and providing students experience with aging as a stage and process. The University of South Carolina School of Medicine's major aim in geriatrics is to prepare students to become skilled physicians in care of older adults. The SMP is embedded into the curriculum. The program introduced medical students to healthy older adults, presented selected health care issues in this population, integrated material early in the curriculum, acquainted students with longitudinal patient care, and introduced students to older adults' living arrangements. The SMP is an effective means of infusing geriatric content into the medical school curriculum and positively affects mentors' and students' attitudes toward each other. This has implications for medical and professional schools, such as nursing, social work, and physical therapy. (Contains 1 table.)
