Volunteering for the Rincon University Marching Band Association is essential to sustaining a high-quality, competitive program that provides students with meaningful educational and performance opportunities. Unlike a typical PTO, which primarily supports general school activities and operates under the school’s umbrella, a 501(c)(3) nonprofit organization like this association exists as an independent entity with a focused mission. This structure allows it to raise funds, secure grants, and accept tax-deductible donations specifically for the band program. Volunteers are the backbone of this effort; they make it possible to manage events, coordinate logistics, support students at competitions, and ensure resources are available where school funding alone falls short. By giving their time and expertise, volunteers directly contribute to the program's success, accessibility, and growth, helping ensure that every student has the opportunity to participate and excel regardless of financial barriers.

How do I become a volunteer?

• To ensure the safety of our students, TUSD requires that all parent and non-parent volunteers complete or update their application each school year. 
• Human Resources reviews your submitted application and works with the school to authorize volunteer work to begin. 
• Volunteer applications may take 2-3 weeks to approve prior to volunteer work beginning. 
• Non-legal guardians must pass a fingerprint background check to be authorized. TUSD provides fingerprinting services. 
• Volunteer approval notices should be forwarded to president@rangerband.org. 
• RUMBA has many volunteer opportunities. Visit our event calendar throughout the year for openings.
