Board and Executive Team

​​​​​​​​Under the provisions of the Presidio Trust Act, six members of the Presidio Trust Board are appointed by the President of the United States. The seventh memb​er is the U.S. Secretary of the Interior or her designee .

Presidentially appointed Board members serve a set term, then are either re-appointed or replaced by whomever is President when their terms expire. In the Trust's two-decade history, the agency has had members appointed by both Democratic and Republican Presidents.
