I've heard not so good things about American Montessori from a friend whom use to work there. Sandy the owner is really biased towards her own children that go there and get's jealous whenever another child out dues her own and she isn't very nice to the employess from what I've heard. I've never had my child there. She's had a few complaints and the State come out and give her a warning or fine too.
Cypress Classical Montessori I've heard wonderful things about.
There are a few in Apple Valley as well that are great I've heard.
I had my own daughter in a Montessori in St.Louis Park and it is definately the way to go for starting out with an early education.
