OASH Regional Offices
Region 4

The Region 4 Office, based in Atlanta, Georgia in Atlanta, Georgia, serves the Southeastern region, which includes eight states – Alabama, Florida, Georgia, Kentucky, Mississippi, North Carolina, South Carolina, and Tennessee – and six federally recognized Tribes.
Region 4 is the most populated among the 10 HHS regions, with more than 20% of the U.S. population. The region has a broad demographic profile and varied landscapes, including coastal areas prone to hurricanes and floods, large urban centers like Atlanta, Miami, and Nashville, and extensive rural areas such as those in Appalachia, the Mississippi Delta, and the coastal plains.
The Region 4 Office works to address key challenges, promote innovations, and protect the health of all communities. This is done by building partnerships and collaborating with state and local public health agencies, other federal partners, healthcare networks, academic institutions, Tribes and tribal-serving organizations, community-based organizations, and others.
