Supporting students throughout their high school athletic journey

Join the Booster Club

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 Without Booster support, teams would have reduced schedules, fewer team levels, outdated equipment, and only basic athletic amenities.

By joining the Booster Club, your support helps provide the following and more: 
  • Referees & transportation (10 vans, fuel, maintenance, buses)
  • Field rentals & facility upkeep
  • Athletic trainer & Hudl video analysis tools
  • Team wishlists & major equipment upgrades 

NEW Digital Booster Membership

Digital membership cards with mobile wallet integration are now emailed to you and serve as free season passes for home, non-CIF games that charge admission.
Support your athlete and their teammates with a tax-deductible membership. All proceeds go back into athletics.
