Harbor Mesa Montesorri is a gem. The true essence of Maria Montesorri's vision is carried out here in a way that nurtures children to flourish. The children at this school learn to appreciate what they have and each other and the world around them through fun and work and song and play. The kind structure makes them feel safe. The administration and staff at this school are so lovely and practical. I am just so happy I found this school for my daughter. It has made a huge difference in helping my daughter love school and learn quickly.
