So Big Co-Op Preschool

We are a non-profit, parent participation preschool in Antioch, CA. We were founded in 1955 by a group of doctors in East County. We've been operating from the same building at the Contra Costa County Fairgrounds since that time. We are run by an all volunteer board of directors under the guidance of a paid teacher/director.

So Big operates on a traditional school year and is closed during the summer.
