We describe a community-oriented primary care (COPC) preventive medicine residency. Through the residency, medical, nursing, dental, and other health professionals work as fellows to combine clinical and public health skills in primary care practices. We describe the steps that fellows used to begin transforming one community health center into a COPC practice, and we highlight the activities of one specific environmental cleanliness project as an example. COPC activities have laid the foundation for further advances in developing a professional partnership between the center and the community it serves.
