Hi A.-
We sent out twins to the Danville Montessori when they were 2. The kids do not need to be potty trained. THe school is located on Camino Ramon. We really loved the school, better yet the twins loved the school. The teachers were great and the curriculum was a good balance of academics and playing. The negatives-expensive and sometimes the director of the school was too focused on money. We never had issues with her, but other families did.
The twins entered Kindergarten this year (public school) and are academically way ahead (they both read, spell, write, perform addition and subtraction), all learned from preschool.
GOod luck with your choice and hope this helps.
