My son has been at NW Montessori House of Children since he was just over 2 years old. Now 4 1/2, he has learned so much not only academically but also socially and behaviourly. The NWM program is not just learning the alphabet and numbers but assisting with potty training (glad we're through with that!), manners, learning about other countries, cultures, nature & space, doing artwork, how to play and get along with others, how to be quiet at times(!), etc, etc. NW Montessori has fun days for the kids throughout the year (i.e. summer splash day) and has special programs in December and July 4th. As a parent, I have felt a true partnership with the teachers of my son's classes. My son's teachers love what they do and I have the utmost respect for them as they help their students grow in so many ways.
Pros: A happy child who loves his teachers and his preschool days.
