Both of my children went to Mesa Montessori starting at age 3. I cannot say enough about this school. My oldest is in high school and my youngest is in Jr. High. Both are in AP classes, getting excellent grades, and like school. Although they have had many wonderful teachers in their lives I stand firm in my opinion that their success is greatly due to the strong foundation they received at Mesa Montessori. If you have any doubts I recommend that you schedule a day to observe the classroom during work cycle.
