About Countryside Montessori School in Great Neck, NY

A better approach to learning since 1998

Building Bright Futures Through Montessori Education

Montessori School Bayside, NY
Countryside Montessori School was established by Sharon Adar Fitoussi who was convinced immediately that the Montessori Philosophy was the most natural way for a child to learn. CMS opened its doors in 1998 in Manhasset, New York with a Primary classroom of 7 students. We moved to our present location in Great Neck in 2001. We currently have two Primary classrooms and two Toddler classrooms with a total of 75 children of diverse cultural backgrounds.

This present location provides us with an estate-like setting that includes an outdoor playground and opportunities for nature walks. We are located on the lower level of the Lake Success Jewish Center. The center has plenty of parking spaces available. In inclement weather conditions the children play in the upstairs ballroom so that they always have an opportunity for movement.

At Countryside Montessori School (CMS), we believe every child has an innate ability and desire to learn. Since 1998, we've provided children with a thoughtful, nurturing environment that fosters curiosity, independence, and a love for discovery. Located in the heart of Great Neck, NY, our school offers a safe and welcoming space where children thrive using the Montessori method, a proven approach that embraces hands-on learning, exploration, and collaboration.


Our estate-like campus features outdoor playgrounds, opportunities for nature walks, and a spacious indoor area for active play on rainy days.
