My daughter attends the Tyndall Center through Berkley schools. It's actually located in Oak Park (just southwest of 11 mile and Coolidge) but owned and run by Berkley Schools. They are a combo daycare center and preschool so no matter what your work situation, they would be good for you. I think the program works that the kids do school work in the morning/early afternoon and then it's "basic" daycare after that for the rest of the afternoon (my daughter is only 2 1/2 right now so I don't know the details on the preschool program since she won't start it until next year). They're open from 7am-6pm. They also have a part time program if you don't want her there every day of the week.
My church also has what I've heard is a good pre-school program. It's First Presbyterian of Royal Oak, located just east of Woodward, south of 11 mile (it's tucked back in a really nice neighborhood). The program is called Sunflowers pre-school, I believe. You don't have to be a member of the church nor do you have to be presbyterian. I believe they are also a combo daycare center/preschool program.
