About Us

The Association of California Symphony Orchestras was founded in 1969 by a small group of committed orchestra managers who believed in the power of personal networking. Almost 50 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 Board of Directors who hail from arts organizations all over the state of California.


The Association of California Symphony Orchestras provides essential leadership and resources to classical music producers and presenters, encouraging and supporting their artistic, organizational, and fiscal development.


The Association of California Symphony Orchestras will be recognized as the pre-eminent leader in providing programs and services to assist, educate, and act as advocate for classical music producers and presenters in California and the region.

As the collective force for orchestras in California and the region, ACSO will be the voice, the forum and the network in service to its members, and the preeminent leader to connect and advocate for its members.
