Hi there,
I took my daughter to a co-op preschool through Pierce College (you can find their info on the Pierce web site online catalog). Since you live in Puyallup as I do, they meet in Midland. It was a great experience though for her and me. It meets once a week for 2 hours in the morning. I think you can still register (I don't think the classes are full yet).
good luck,
C.
