The Board of Trustees serve as custodians of the integrity of the school, holding in trust the school’s future as well as its present. Their collective judgment respects the interests of constituents who are to come and of the larger society that all independent schools serve. It is responsible for establishing and reviewing the philosophy and objectives of the school, for effective implementation of the policies that it sets forth, and for the school’s fiscal well-being.
The board is comprised of a minimum of 12 members, selected from the parent body and the community at large, plus the head of school, who also serves as president. Each trustee is elected to a two-year term and is limited to three consecutive terms. Below are bios from our current trustees and trustees emeriti.
