About Us

Our School

Dear Visitors,

Welcome to Cornerstone Montessori School, located at 240 Sickle Lane, Deptford, NJ.  

We offer an exceptional Montessori Early Childhood (preschool/Kindergarten) program for children between two-and-a-half to six years old.

What makes Cornerstone Montessori special is its small class size and its close-knit community of parents. Our experienced instructors guide our students with warmth and respect.

Cornerstone’s top priority is to ensure that every day counts and that each child can learn and develop successfully as an independent student. We believe that the foundation we lay for our students can and should hold fast through a lifetime of learning.

Our aim is to teach children the skills they will need to become self-directed learners, flexible thinkers, creative problem solvers, resilient individuals, and empathetic citizens of the world.

Cornerstone Montessori School is an American Montessori Society (AMS) Full Member School and a proud member of the Gloucester County Chamber of Commerce.
