The Health Resources and Services Administration (HRSA), an agency of the U.S. Department of Health and Human Services, is the primary federal agency for improving health care to people who are geographically isolated, economically or medically vulnerable. HRSA programs help those in need of high quality primary health care, people with HIV/AIDS, pregnant women, and mothers. HRSA also supports the training of health professionals, distribution of providers to where they are needed most, and improvements in health care delivery.
