Supporting students throughout their high school athletic journey

Join the Booster Club

The San Marcos Athletic Booster Club directly funds the extra costs that keep high school sports running safely and competitively. Without Booster support, all teams would have reduced schedules and team levels, outdated equipment, and only basic athletic amenities.

*NEW Digital Booster Membership* 

Membership cards are now digital and sent via email, featuring mobile wallet integration. Your digital membership card will serve as a season pass to gain free entry to home, non-CIF games for those sports that charge admission.
Support your athlete and their teammates with a tax-deductible membership. All proceeds go back into athletics.
