Board of Trustees

The ADA’s managing body responsible for the association's success and growth.

The Board of Trustees is the managing body of the Association, vested with the power to conduct all business of the Association, subject to Illinois law, the Association's governing documents and the mandates of the House of Delegates. The Board consists of 17 trustees (one from each trustee district), the President-elect, the two Vice Presidents and the New Dentist Committee Chair—as the voting members of the Board—and the President, Treasurer and the Executive Director as non-voting members of the Board. The Board traditionally meets seven times during the year.
