The Rosin Club is the Centaurus High School Orchestras Booster Club organization. In the 2025-2026 school year, it is estimated that 30% of our students are eligible for free or reduced-price lunch. The Rosin Club aims to make orchestra music and performance accessible and enriching to all interested students. The Centaurus High School Orchestras operate with limited support and resources from the school district. As a result, we are often tasked with purchasing instruments and supplies, paying for maintenance and repairs of equipment, paying for transportation to events, and more. In addition to program support, we offer scholarships to students in need to assist with the purchase of their uniforms, instrument rentals, and sectional teacher fees.
