The Association of California Symphony Orchestras was founded in 1969 at Asilomar by a small group of committed orchestra managers who believed in the power of personal networking. More than 40 years later, ACSO remains the hub of California’s vibrant classical music community by providing a variety of services to its 400+ members including networking, mentorship, resource sharing, advocacy, and professional development. Membership is open to orchestras, choruses and classical music presenters of all sizes, symphony leagues and guilds, youth orchestras, festivals, artist management firms, businesses, and individuals associated with orchestras or wishing to access our services. ACSO is governed by a 21-member Board of Directors who hail from arts organizations all over the state of California.
