“I have been blessed in my life in many ways. I have a wonderful family and the opportunity to manage a school that is making a difference in the lives of children in our community by preparing them for lifelong success and happiness.
I was introduced to the Montessori philosophy by chance through a friend. I was very impressed and decided to pursue a career that involved Montessori education.
I continue to learn more about the approach to Montessori-based education every day. It is very heartening to know that recent neuropsychological research in brain development and education paradigms advocated by leaders in the field are validating the approach to children’s growth and learning that was developed by Maria Montessori over a hundred years ago.
It is a pleasure to be a part of a community where love of learning is at the heart of what we do.”
