FAMILY-OWNED SINCE 1976 · THREE ST. LOUIS SCHOOLS
Montessori child care for ages 6 weeks to 6 years, across three hands-on St. Louis locations. Infant, toddler, preschool, and summer care, all year-round.
Four programs, one philosophy: real Montessori, start to finish.
From as young as 6 weeks old, your baby gets a dedicated infant room, small groups, and teachers who notice the little things. It's a soft landing for both of you.
Independence through repetition: pouring, buttoning, tidying, and the simple routines that make a two-year-old feel capable.
The full five-area Montessori curriculum in a mixed-age classroom, where older children teach younger ones and everyone moves at their own pace.
…and then there's summer
Summer doesn't mean a break from curiosity. Our 10-week summer program runs June through August with a new theme each week, keeping preschoolers active, engaged, and ready for what's next.
Since 1976, three St. Louis schools built for the smallest hands and the biggest questions.
I visited several schools before choosing Casa Dia Montessori. And I wouldn’t send my daughter anywhere else. Her teachers are amazing and the school’s Headmistress is competent, smart, and caring. I feel comfortable leaving my daughter in the staff’s care. And she is learning so much.
I am very happy with Casa Dia. The Directress and Teachers always keep us informed of what is going on. My son has Type 1 Diabetes and the staff has been outstanding working with his medical needs. We would recommend Casa to anyone. Thanks for making us so welcome.
Really enjoy the teaching and learning style at CAC. My 2 year old has excelled with her ABCs, drawing, singing and cleaning up. Social interaction is great and she obviously has confidence from what she learns.
A lot of places borrow the name. We live the method.
Every classroom, every room, the same genuine method. No franchise, no shortcuts.
Your child's name, not a file number. Same family running the schools since day one.
Materials kids touch, move, and choose. Learning that looks like play, because it is.
Six weeks old through pre-K, plus weekends and summer. One place, the whole way through.
Montessori is not a set of subjects taught in turn. The five areas live together in the same room, and each child moves through them in whatever order suits their day.
No staged photo shoots. Just our classrooms and playgrounds on a regular week.
Short walk-through videos of each of our schools, filmed by our own staff.
All three of our schools in the St. Louis metro area share the same Montessori philosophy and the same warm, family feel.
