Hi A.,
Our family just moving to Allen and I just went through process of checking out preschools for my 15-month-old daughter. I finally chose Allen Montessori Academy, off Greenville on Pebblebrook, east of I-75. I really don't know much about Montessori, and the places vary in how they interpret the teaching philosophy, but this one seemed very homey, seemed to have low turnover and great sense of community, well-established. We signed up there.
On the other hand, we haven't actually been enrolled yet (June).
Good Luck!
