Board of Trustees

As an independent school, the San Francisco Schoolhouse is governed by a Board of Trustees. The Board’s primary responsibilities are to ensure the school’s financial health, to work with the Head of School in developing a long-term strategic plan for the school, and to support and evaluate the Head of School’s development and performance. The Board approves the annual operating budget, takes a leadership role in fundraising, and participates in planning and maintaining the school’s physical plant.

With the birth of her third child she gave up the corporate world. At the same time her oldest child embarked on kindergarten. After looking at all the school options, she became passionate not only about a true progressive education but about a school where parents are an integral part of the journey along with their children. With that in mind, she teamed up with Rebecca Dake, another founding parent, to start the San Francisco Schoolhouse. Two of her children attend the Schoolhouse.
