The National Park Service Office of Public Health (OPH) is a national activity headquartered in Washington, DC. Functioning as an internal health department, OPH provides agency specific capabilities for parks on a range of new and evolving public health issues through prevention and response services. The OPH also promotes the health and well-being of our park visitors by illuminating and encouraging ways to use our public lands for physical, mental, spiritual health and social well-being.

Underlying all of its efforts, the OPH strives for a One Health model of public health practices and integrative effort of multiple disciplines, working collaboratively to attain optimal health for people, animals, and the environment. We are proud that the work we do everyday saves lives and helps address public health issues impacting more than 300 million people each year.
