Supporting students throughout their high school athletic journey.
Every Sport, Every Athlete
High school athletics do more than build strong athletes — they shape well-rounded, successful adults. Sports promote physical and mental well-being, academic achievement, leadership, teamwork, and the development of lifelong skills.
The San Marcos Athletic Booster Club bridges the funding gap for all San Marcos High School sports programs—covering critical costs the school district can’t, including:
Referees & transportation (10 vans, fuel, maintenance, buses)
Field rentals, green fees, and facility upkeep
Athletic trainer & Hudl video analysis tools
Team wishlists & major equipment upgrades
Every sport benefits — whether through free game access, field rental support, or vital resources behind the scenes.
Together, we fund the future of San Marcos High School athletics.
Join today—every membership makes a difference.
The San Marcos Athletic Booster Club will host a Hall-of-Fame fundraiser event honoring alumni athletes on October 17, 2026. Stay tuned for more information.
Join the Booster Club
Purchase a San Marcos Athletic Booster Club membership and support your athlete and their teammates with a tax-deductible membership. 100% of proceeds go back into athletics.
NEW Digital Booster Memberships
Memberships will now be delivered via email in digital format instead of a physical card and can be added to your mobile wallet for ease of use. Your digital booster membership will serve as a season pass to gain free entry to home, non-CIF games (where applicable).
-
Royal Cards are for current San Marcos High School students and can be purchased on the San Marcos High School website. They include benefits exclusively for students.
Whereas the Booster digital season pass is a perk for athlete family members and alumni which allows for free entry to home, non-CIF games (where applicable).
-
The requested donation is $100 per athlete. Our membership types include options for multiple athletes. Only one membership type can be purchased at a time. For additional memberships, please place a new order. Unsure of which membership to buy? Email smhsabc@gmail.com for help.
-
Our system does not have a “cart function” to add multiple types of memberships. Please place individual orders for each membership type.
-
Yes! If you are unable to access the digital membership on a mobile phone, please email smhsabc@gmail.com to arrange for a physical card.
-
Every athlete and athletic program is benefiting from the support of membership purchases equally whether we charge for your athlete’s sport or not. It is not logistically possible to charge for every sporting event, however due to the budget deficit, more entry fees to sports and premium games are being added.
-
Please email smhsabc@gmail.com. We are happy to help you with your membership selection and answer any questions.
If every athlete was covered by a Booster membership, unfunded district costs would be covered, keeping our sports programs strong.
A perk of membership includes a digital season pass. This digital pass provides FREE admission to non-CIF home games for those sports that charge admission, so you can bypass lines and not hassle with paying extra fees that GoFan, the high school sports ticketing system, charges.
This year, we will charge gate fees for additional sports and premium games, which will increase the value of membership.
