What We Do

The National Park Service Office of Public Health delivers the highest quality professional public health services to protect and promote the health and wellbeing of visitors who come to enjoy our parks. Comprised of DC based staff in the Washington Support Office (WASO) and Commissioned Corps officers who work at the regional or park level, the Office of Public Health executes its work through three branches: Health Promotion, Epidemiology, and Field Services. The Health Promotion Branch aligns under the focus area of Health Promotion and is comprised of Healthy Parks Healthy People and the Your Park! Your Health! Program. The Epidemiology Branch and the Field Service Branch align under the Health Protection & Disease Prevention focus area for OPH. In addition to carrying out the numerous public health efforts in parks, the Office of Public Health serves as the official personnel office and primary liaison to the U.S. Surgeon General for all U.S. Public Health Service (PHS) Officers assigned to the Department of the Interior.
