My son goes to Angels Christian Academy at Sunridge Heights and Eastern. I am very happy with it. The teachers are good and my son loves going there so much he is upset on the weekends that he can't go.
We have also used Kiddie Academy on Coronado Center. I don't have anything bad to say about it, the teachers and director were nice, but my son had a fit every day when I dropped him off. We switched to Angels because they have a kindergarten program that I wanted to get him in to and now he hardly even says goodbye when I drop him off, he's so excited to be there.
My daughter went to Creative Kids on Wigwam. We had some issues with them, but at that time it was the only center in the area so we were stuck. That was about 4-5 years ago so I can't really say what it's like now.
