About our Trustees

Since its founding, UFS has been governed by an independent Board comprised of individuals dedicated to the Quaker values, founding philosophies, and spirit at the foundation of United Friends School. Our Trustees include original school founders, alumni, and current parents, caregivers, community members, and members of the Religious Society of Friends. The Board meets online on the second Thursdays of September, October, November, January, February, April, May, and June. Following are the UFS Board of Trustees’ profiles:
