The Wildcat Booster Club is a 501c3 non-profit fundraising organization that exists to support and enrich the extra-curricular high school experience for our kids while they attend Mount Si High School. Parents, alumni, and the community are encouraged to donate, and volunteer. All donations are 100% tax-deductible.
All donations go to promoting extra-curricular interests for our students at Mount Si High School.
