Community-Powered. Wildcat Strong.

Partners play a crucial role in the success of Mount Si High School Wildcat football, providing financial support that enables the team to thrive on and off the field. Contributions help cover costs for player equipment, coaching development, off-season training camps, academic support, scholarships, and more.

Building Champions: One Valley, One Team, One Family

The mission of the Booster Club is to promote the highest level of achievement for Mount Si High School football by providing fundraising, volunteer support, communications, and by fostering fellowship between coaches, players, their families, and the community. Every contribution helps shape the future of our athletes—on and off the field.
