Welcome to Cornerstone Montessori School!
Cornerstone Montessori School Provides residents of Sewell, NJ and surrounding communities with preschool, kindergarten and early elementary services for children between two-and-a-half to ten years old.

Cornerstone uses a “whole child” approach to education and care to instill each child with a sense of self-respect, independence, acceptance, and community through hands-on and self-guided curriculum. At Cornerstone, each child is a unique individual deserving respect, honor, and care.

Cornerstone Montessori School is dedicated to enriching the lives of preschool-, kindergarten-, and early elementary-aged children through the following guidelines:
  • Provide healthy, positive learning environment by stimulating their learning ability to its maximum potential
  • Prepare the children to be respectful, responsible citizens.
