I am happy with Tomorrow's Kids Montessori in Eagan. It is on the corner of Lexington and Wescott Rd. I would reccomend you checking it out. They take kids age 33 months to 6. It is pre-school focused. My first son that went there went for a full year of preschool as a four year old, and now is in kindergarten and goes to morning kindergarten and then back to the school for the afternoon. Next year he will go to first grade full time at his elementary school. It has been a really good transition.
