I used Chesterbrook Academy in Lisle. They closed the location I used (it was on Karnes) and moved the staff to the facility on Lacey. I loved the curriculum. I only pulled my child out because I ended up staying home.
We toured the Three in One center in Plainfield on 127th and loved it. They are independent, however. They were VERY reasonable priced.
Try Creative World, there is one in Aurora and Plainfield
