CASA DIA MONTESSORI OF MEHLVILLE · FAMILY-OWNED SINCE 1976 · AGES 6 WEEKS TO 6 YEARS
Casa Dia Montessori of Mehlville sits on Kinswood Lane in Mehlville, just off South County Center's shopping corridor and a short drive from Cliff Cave Park. Families choose our school because it treats a six-week-old and a five-year-old the same way: as capable of real learning, right now. Every classroom is built around that idea, and every teacher on staff is trained to protect it.
At Casa Dia Montessori of Mehlville, the five areas of the Montessori curriculum aren't taught one after another. They share one room, and your child decides which one to explore first.
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.

Dear Parents,
Hello! It is our privilege to work with the staff and families of Casa Dia Montessori. It is often said that it feels comfortable and friendly here. It is our goal that every family feels comfortable with their children at Casa. We endeavor to care for your children as if they were our own.
One of our strengths in this area is the longevity of our staff. They are a very committed group; several of them have been here for many years serving families with excellent care. It is our joy to now serve a second generation of families. Casa Dia Montessori is dedicated to developing each child using the Montessori method.
Center Director
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.
I have a 2 year old and a 4 year old going to Casa Dia Montessori and I couldn’t be happier. The facility is very clean, the food they serve is healthy, the teachers are top notch and my children love going to school there. No child care center’s rates are good, but they are extremely competitive for what their competition is. they are actually lower than any of their peers in the industry. Can’t say anything more than I wouldn’t go anywhere else.
The staff at Kinswood is remarkable! My child enjoys coming to school and learning. The staff always keeps in touch with how he is doing and truly care about my child.
