Cow Hollow School a school for children 2-5 years old, supports the belief that children learn through play, exploration and discovery within the context of nurturing and reciprocal influences of children, parents and teachers. Our curriculum is based on the constructivist philosophy in which children construct knowledge and understanding from authentic experiences—they are encouraged to explore possibilities, invent solutions, collaborate with others, and try out ideas in the context of meaningful experiences. These real-life experiences make connections that inspire and provoke, and foster inquiry and critical thinking.

We hold an image of the child, the parent, and the teacher as competent and active participants in learning and creating the culture of our school. Parents act as partners in the classroom, working alongside the teachers about once a month in the 2/3 and 3/4 year old classes, and five times per year in the 4/5’s classes. Parents are given an opportunity within the low adult-child ratio to closely observe and learn from and with their children with support and guidance from experienced teachers. As a result of this unique setting, partnership and experiences, learning, teaching and parenting are enriched and transformed.


Early Days of Cow Hollow

Founded in 2000 by a group of remarkable San Francisco women, Cow Hollow School was born out of the need for a creative, play-based program for young two-year-olds. The overflowing enrollments of other local preschools with programs for young two-year-olds, and the appeal of a parent participation format for very young children, convinced the founders that there was enough need and interest in San Francisco to create a new school.   After coming to an agreement with the Vestry of St. Mary the Virgin Episcopal Church, the Preschool was able to open for a one-year trial with 12 children. During that first year, the volunteer Board poured an enormous amount of time building a school, soup to nuts—defining and implementing a play-based program, developing a school philosophy, hiring the teaching team, working through the myriad of licensing issues, recruiting families, and raising their own families!  Needless to say, it became apparent that the school had a future.

Move to the Presidio

​In ​2004, in order to actualize and make evident ​​our belief ​in children as active participating members of a rich and diverse society, we started our search for a space that would reflect this within and outside of its walls. ​In 2005 we moved into ​a beautiful historic building in the Presidio. ​Our first location was small and only could house one class of children at a time (less than forty families total) and required that church parishioners ma​k​e up a ​the majority of the school population​. Our move to the Presidio ​meant that enrollment ​would double in size and become accessible to any and all Bay Area families​.
