Tamalpais Preschool is a private, nonprofit pre-school and pre-kindergarten that has been in continuous operation since 1956, making it one of the oldest independent preschools in Marin. Although it is non-sectarian, the school was built by and is housed by the Mt. Tamalpais United Methodist Church.
The school's teaching philosophy, based on the work of Swiss developmental psychologist Jean Piaget, is a child-centered approach that provides activities to engage learners. It also presents challenges that actively involve children, engages children in the appropriate state of motor or mental operations and puts children in small groups that help them see things from other children's perspectives.
