In the founding years of San Francisco Schoolhouse, Rebecca Dake simplified the definition of an excellent education down to two basic ingredients: a passionate, experienced teacher, and a safe and healthy room. As the Schoolhouse has grown over the years, we have assembled a team of multi-talented individuals who work in cooperation with each other and with the children and their families, sharing their passions and their vast experience with life, learning, and progressive education. Learn more about each member of our team below. Continue reading beyond that to learn about the members of our Board of Trustees.

As an independent school, the San Francisco Schoolhouse is governed by a Board of Trustees.

The Board approves the annual operating budget, takes a leadership role in fundraising, and participates in planning and maintaining the school’s physical plant.

Erin Cooney, Board President, earned her B.S. at the Wharton School of the University of Pennsylvania and spent 19 years working in accounting, finance and sales operations for public accounting, start-ups and software companies in the Bay Area. 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.
