OASH Regional Offices
Region 1
The Region 1 Office, based in Boston, Massachusetts, serves the New England region, which includes Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont, as well as 10 federally recognized Tribal nations. New England is geographically compact and densely populated with more than 14 million residents within 71,000 square miles, and containing three of the four most densely populated states in the nation (MA, CT and RI).
New England’s unique geographic configuration means that in a single drive of 250 miles, five of the six state borders are crossed. Individuals and families often live in one state while working or receiving health care in another. As a result of this border permeability, the New England states must work together to harmonize health policy and messaging across the region.
Health care delivery, clinical research, development of new technologies and pharmaceuticals, and the education of our nation’s health care professionals have been priorities in New England for decades. Additionally, New England hosts some of the premier public health and medical schools in the nation, as well as some of the most innovative state and local public health agencies, positioning the region at the forefront of public health transformation. Whether as the birthplace of the first modern community health center in Dorchester, MA in 1965, or the first region in the nation to have a community health worker (CHW) coalition, New England has been at the cutting edge of progressive public health policy and financing.
