About the Public Health Agency
The Public Health Agency (PHA) is a dynamic, multi-disciplinary organisation dedicated to improving and protecting the health of the population. As part of the health and social care family, we work closely with the Strategic Planning and Performance Group (SPPG) of the Department of Health (DoH), local Health Trusts (HSC Trusts), the Business Services Organisation (BSO) and the Patient Client Council (PCC), and other partners to drive meaningful change across Northern Ireland.
Guided by our vision of a healthier Northern Ireland, our purpose is to protect and improve the health and social wellbeing of our population. We are committed to reducing health inequalities through leadership, partnership, and evidence-based practice.
