So Big Co-Op Preschool

So Big Co-Op Preschool So Big Co-Op Preschool is a parent owned and operated, non-profit, non-sectarian, parent cooperative

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.

Hello everyone. My name is Jessica. My beautiful little girl Bennett was a student of Miss Marys pre school for 2 years! I cannot say enough things of how amazing So-Big and Miss Mary were for her kindergarten readiness. My daughter just started kindergarten and on day one we were informed that she is the most locked in and ready for kindergarten. I couldn't be more thankful for the way So-Big helped her prepare for school! If you're looking for an amazing pre school that offers kindergarten readiness SO BIG IS THE PLACE TO BE! Thank you Miss Mary for everything you have done for our girl!

We still have space for your toddler to join So Big for the school year. Tours can be scheduled during our open hours. If you are interested in a tour please send us a quick message here and someone from our staff will reach out to you!

We have 6 baby chicks! Wanna take a guess on what our students will name them this year?
