Background and Who They Are

The Think Tank is composed of professionals with diverse backgrounds in tribal public and environmental health. The group was originally established in 2011 as the National Tribal Environmental Health Think Tank by the Office of Tribal Affairs within the Centers for Disease Control and Prevention's National Center for Environmental Health and the Agency for Toxic Substances and Disease Registry. In 2015, the Think Tank decided to expand its focus to include broader public health issues, reconvening as the Tribal Public and Environmental Health Think Tank in alignment with CDC’s Tribal Support Unit in the Office for State, Tribal, Local and Territorial Support.
