CASA DIA MONTESSORI OF CRESTWOOD · FAMILY-OWNED SINCE 1976 · AGES 6 WEEKS TO 6 YEARS
Casa Dia Montessori of Crestwood sits on Watson Road at the edge of Crestwood, in Sunset Hills, minutes from The Magic House. 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 Crestwood, 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.

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.
It’s hard to put into words how grateful we are for the love, care, and guidance Michael has received over the past three-plus years. This school has been such a positive and nurturing place for him, and we’ve truly cherished watching him grow and thrive here.
This daycare is by far the nicest daycare I have ever been to. I love that I can call to check on my boys everyday and no one complains of all my calls. I am very comfortable with my sons’ being at this center while I am at school.
Still wondering about something? Schedule a tour and ask us in person. Bring your child, too.

Yes. Our infant and toddler rooms are built for children just starting out, with small groups and teachers trained to ease that first transition.
