Trust, Earned One Family at a Time

“Our daughter walked in shy and came out asking to set the table at home. The teachers see her, not a class list.”
Megan R. · Crestwood family
“We toured five schools. This was the only one where the classroom looked the same with us standing in it as it did without us.”
Daniel P. · Chesterfield family
“Both of our boys started in the infant room and stayed through pre-K. Four years in, it still feels like family.”
Alyssa T. · Mehlville family
“Real Montessori materials, real patience. Our son reads now and nobody ever sat him down and made him.”
Chris and Jenna M. · Crestwood family

Why families stay

The NA Montessori Difference

A lot of places borrow the name.
We live the method.

01
Real Montessori
Every classroom, every room, the same genuine method. No franchise, no shortcuts.
02
Family-owned since 1976
Your child's name, not a file number. Same family running the schools since day one.
03
Hands-on & child-led
Materials kids touch, move, and choose. Learning that looks like play, because it is.
04
Every age, all year
Six weeks old through pre-K, plus weekends and summer. One place, the whole way through.

Five Areas, One Classroom

The Montessori curriculum isn't a set of subjects taught in turn. All five areas live together in the same room, and each child moves through them in whatever order suits their day.

  • 01

    Practical Life

    Pouring, buttoning, sweeping: the ordinary work of becoming independent.

  • 02

    Sensorial

    Sorting the world by size, sound, weight, and shade, until the differences are obvious.

  • 03

    Language

    Sounds before letters, letters before words, and writing before reading.

  • 04

    Mathematics

    Quantity you can hold in your hands before quantity on a page.

  • 05

    Culture

    Geography, botany, music, and art, treated as one continuous subject.
