Our philosophy is founded on traditional montessori guiding principles. It is designed and operated using those principles, as well as authentic montessori methodology and educational materials.
Our mission is to cultivate the natural desire to learn and to foster a lifelong love of learning in every child.
And our vision is to plant the seeds of exploration and discovery that will enable children to understand the world and find their place in it.
Our teachers are accredited through MACTE (Montessori Accreditation Council for Teacher Education), the premier, international standard-setting and accrediting body for Montessori teacher education.
