Who We Are

North Shore Montessori School Mission Statement

North Shore Montessori School was founded in 2007 by Margaret Henry, the director and head Children’s House teacher of North Shore Montessori School. Our mission is to develop the whole child in an environment based on the Montessori Philosophy and Methodology originally developed by Maria Montessori. Our primary goal is that all of our students become confident lifelong learners, with a deep respect for themselves, others, and the world in which they live. Our focus in applying Montessori principles is to give each child the opportunity to be nurtured, educated and inspired at his or her own unique pace in order to optimize their personal educational experience.

“The greatest sign of success for a teacher is to be able to say, “The children are now working as if I did not exist.” ― Maria Montessori

“It is not enough for the teacher to love the child. She must first love and understand the universe. She must prepare herself, and truly work at it.” ― Maria Montessori
