EBYO, East Bay Youth Orchestra, is a community-based nonprofit organization started by parents, teachers and music professionals to augment school instrumental programs of San Francisco East Bay and the surrounding communities.  EBYO provides high quality group instrumental instruction and symphonic orchestral experience.  EBYO is governed by its Board of Directors, who are responsible for policy determination and administration of the Orchestra.

All Groups meet once a week from mid-September through May. Concert Orchestra and Symphony Orchestra rehearse at California State University East Bay Campus located in the East Bay Area in Hayward, California. Rehearsals vary in length from 60 minutes for group instruction to two hours for the most advanced group.

EBYO holds five public concerts each year, in September, November, December, March and May.
