B.S.
If you don't mind going a little farther, I would recommend Country Tyme Early Education Center in Limerick, PA. It is right near the Limerick exit on rte 422. Currently I only have a child in the 2 yr old age group, but we have been very happy with the place. I'm sure the pre-K group is just as good. They also offer a hot lunch which has been wonderful so we don't have to worry about packing one every morning.
