Environmental Health Officers (EHOs) in the United States Public Health Service (USPHS) Commissioned Corps prevent illness and injury across the nation and around the globe. Approximately 350 EHOs work in general environmental health, health promotion and disease prevention, injury prevention, and occupational safety. We also work in highly specialized areas such as counterterrorism, emergency management, health physics, hazardous waste operations and emergency response, environmental compliance and sustainability, industrial hygiene, food safety, infection control, and biomedical and epidemiological research. During natural disasters and other emergencies EHOs protect the public from environmental threats and help communities recover, and we also frequently deploy as safety officers to protect our fellow emergency responders. As an EHO in the USPHS Commissioned Corps you’ll find meaningful experiences and frequent opportunities to make the world a better place. As part of a unique team of committed public health professionals, you’ll enjoy leadership opportunities, excellent benefits, and work/life balance, all while improving and advancing the health of the Nation.
