The Cal High Instrumental Music Program offers students life-changing, world-class experiences through the power of music. Open to all Cal High students, our program is built on a foundation of excellence, inclusion, and fun—helping students grow not only as musicians, but as confident, connected individuals.

​

From inspiring concert performances to high-energy field shows and spirited parades, our students bring music, heart, and school spirit to everything they do. When you join the Cal High music program, you become part of a vibrant, welcoming community. Students collaborate, perform, and travel together—building lasting friendships and unforgettable memories.

​

Whether you’re performing in a packed stadium with the Marching Grizzlies, captivating a concert hall audience, or competing in a jazz festival, you’ll be surrounded by teammates who push you to be your best. Our program celebrates every student’s growth, and we believe that when young people come together to create music, they create something truly magical.

​

Students can explore a wide variety of instrumental music courses, including Marching Band & Color Guard, Concert Band, Symphonic Band, String Orchestra, Jazz Band, and audition-based groups such as Wind Ensemble, Chamber Orchestra, and Jazz Ensemble. No matter your musical interest or experience level, there’s a place for you here.

Guiding and supporting our students is a dedicated instructional team that brings both expertise and passion to every rehearsal and performance. Bob Grigas leads the program as the Instrumental Music Director, with Lori Willis serving as Orchestra and Choir Director, and Briana Berastain as Marching Ensemble Co-Director.

 

Together, they foster a supportive and challenging environment where students can grow musically and personally.

​

Our program is also backed by a committed Booster Club, made up of Band, Color Guard, and Orchestra families who believe deeply in the power of music education. The Boosters play a vital role in fundraising, organizing volunteers, and assisting the directors with event planning throughout the year. Every family with a student in the Cal High Instrumental Music Program is automatically a member and is encouraged to participate. Booster meetings are held monthly during the school year beginning in August.

Come make music, make memories, and make lifelong friends at Cal High. We can’t wait to see what you’ll create.
