GHS Clef Club Boosters

The Glendora High School Orchestra Booster Organization is a vital part of our music program, providing support that helps our students thrive both on and off the stage. Without your help we would not be able to put on as many performances as we do!

How Can I Help?

Whether you have a few hours to give or want to be more involved throughout the year, there's a place for every parent to make a difference.

Opportunities include photographing concerts, ticket taking, helping at concerts, chaperoning on trips, putting on the banquet, or helping to make decisions by joining our boosters board—no experience is necessary, and every contribution is appreciated.

Boosters support 7-8 concerts throughout the year. If each family volunteered at 1 event, we can easily make this year a success. Together, we can ensure the orchestra program continues to grow and flourish for years to come!

GHS Mariachi Corazón del Valle Sound System

Your gift helps bring a full, professional sound to the GHS Mariachi ensemble.  By supporting this sound system, you’re giving student musicians the tools they need to be clearly heard at concerts, school events, and community performances. As well as the tools to learn how to set up for performances and properly use the equipment.

Every contribution moves us closer to a reliable, high-quality setup that matches our students’ hard work and talent. Thank you for standing behind music education at Glendora High School and helping our mariachi shine onstage.
