Hello there, ahh school. I have a just turned 4 year old and am quite particular about the educational surroundings of our son. I enjoyed 2 schools in the Concord area this year. Clayton Valley Presbyterian Preschool on Ygnacio, but past Safeway on the same side. Great program, great teachers and very good price, bring your own lunch. Compared to another program at KinderCare on Concord Blvd, this one is a bit more but there is more food provided, lunch and a hot breakfast for the kids who get there in time. KinderCare does a bit more on the studies but both places we like. Good Luck and don't let him see you cry when you drop him off... you will be fine! A.
