I have a four and a half year old son, and he loves Trettin preschool. There are always new and exciting activities and projects going on for him to do, and he comes home with adorable projects that go along with the current curriculim of the week. They have a daily schedule that includes morning and afternoon story and show and tells, which he loves. Make sure your child gets to check out O-Hall, it's an indoor playground with bikes and climbers. Just wonderful.
I was welcome to come in and help him get comfortable with his new surroundings as long as I needed too, and his teachers were very helpful. I would highly recommend the preschool to anyone. It is a drop in preschool so you can use it just how you need it, on occasion or regularly, and you don't need to be on any kind of waiting list either!
