This paper presents the Adults' Health and Developmental Program (AHDP), an established health program which could serve as a model to be emulated throughout the nation. The AHDP is located at the University of Maryland. It is inexpensive to operate, simple in design, health related, provides services to older adults, training for students interested in gerontological health, and research opportunities. Once enrolled, older adult members and students (staff) continue to return so that turnover is relatively low compared to other voluntary organizations. The potential for building on additional health services is unlimited. The Program is seen as having preventive, interventive, and postventive or rehabilitative health care aspects. (Author)
