Tribal Technical Advisory Committee

SAMHSA's Tribal Training and Technical Assistance Center

The Tribal Technical Advisory Committee helps build and maintain SAMHSA’s government-to-government relationship with American Indian and Alaska Native tribes.

In 2008, in recognition of Presidential executive orders and memoranda on tribal consultation, SAMHSA formed the Tribal Technical Advisory Committee (TTAC) to enhance the government-to-government relationship and honor the federal trust responsibilities and obligations to tribes and American Indian and Alaska Native people.

The SAMHSA TTAC membership, made up of 14 elected tribal leaders from federally recognized tribes, provides a venue where tribal leadership and SAMHSA staff can exchange information about public health issues, identify urgent mental health and substance abuse needs, and discuss collaborative approaches to addressing behavioral health needs.
