Hi S.,
Welcome to Oak Park! We have a wonderful preschool right here in town. It's called Oak Park Neighborhood School (not to be confused with Oak Park Comm. Center Preschool). It's on the corner of Kanan and Churchwood on the campus of Oak Hills elementary school.
The school follows the Reggio Emilia philosophy (you can learn about it online) which encourages children to ask questions,think and find out answers to questions through guided exploration. We are really happy with the program.
If you want to learn more about the preschool, I'd be happy to tell you more. School starts next Tuesday if you want to come and visit the school.
Good Luck!
M.
