Public Health Nurses aim to improve the health of individuals and diverse communities locally and globally through leadership and excellence in nursing education, research, practice and service. While most nurses care for one patient at a time, public health nurses care for entire populations. By working with whole communities, public health nurses are able to educate people about health issues, improve community health and safety, and improve access to care.

Public Health Nurses provide services in the home, school, and community settings. The Public Health Nurse coordinate their services with medical and other professional personnel within the hospital and clinic. They also coordinate services with other non-IHS resources, such as Tribal, State, Federal and private health services and programs. Along with providing home visits in the community, Public Health Nurses also aim to empower and support the needs of the community thru educational programs, projects and community screenings/outreach events.
