    About Tam High Foundation

    A defining feature of Tam High Foundation’s grantmaking is its direct support for Tamalpais High School and the Tamalpais Union High School District, with recent awards reaching six figures and flowing to school entities in Mill Valley and Larkspur. The foundation is a parent-led independent 501(c)(3) fundraising organization that supports academic excellence and the emotional and physical well-being of Tam students through programs, tools, and equitable educational opportunities. Recent grants show that it funds both large institutional needs and smaller school-based support, with the high school and district appearing repeatedly in the largest awards on file. Its work sits close to the school community: grants are reviewed twice a year and funded from community donations. The foundation also backs initiatives that connect classroom practice with student experience, including technology, guest teachers, equity, wellness, and other initiatives serving students. Recent recipients include Tamalpais High School and Tamalpais Union High School District, alongside school-affiliated groups such as Tam High PTSA and the Tam High School Association. The pattern points to a funder focused on strengthening the high school ecosystem through partnership with faculty, staff, and parent-led support structures.
