Meet Our Trustees

Exeter is fortunate to have a dedicated body of alumni volunteers, with diverse and expert backgrounds, to oversee the administration of the school and the management of its financial and physical resources.

There are 21 Trustees, and the group consists of the principal, who is appointed by the Trustees and serves as a member for the duration of his tenure; 17 term trustees, who serve one or two five-year appointments; and the president and two vice presidents of the General Alumni Association (GAA), who are elected by that association’s board of directors. These GAA-elected trustees serve one or two terms of two years.

Our current Trustees share a passion for Exeter’s mission, a belief in the potential for transformation and discovery within all of our students, and a vision for Exeter’s ongoing excellence and leadership in secondary school education.
