OCCC was founded in 1985 as a 501(c)(3) non-profit, tax ID number 77-0214313, based on a choral group to serve the city of Campbell and other Santa Clara Valley communities. Our seasonal concerts, one at Christmas and one in the spring, allow our members to share their musical talents with the larger community, and to reach their own creative potential through artistic performance. Our spring concerts feature a diverse selection of​ musical programs, including Disney, Broadway, Country, Jazz, Rock n Roll, and Folk music. Our Christmas concerts highlight various holiday music, both secular and spiritual.  One of OCCC's primary objectives is to promote charity to the larger community, through our musical performances.
