Why families choose Mehlville
Mehlville, MO
Casa Dia Montessori of Crestwood sits on Watson Road in south St. Louis County, 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.
- Minutes from The Magic House, off Watson Road
- Six weeks through six years, all in one building
- Every lead teacher Montessori-trained and credentialed

A Letter From Our Director
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.
Sincerely,
Center Director

Toddler Care
Once your toddler is on the move, they step into a room built for exploring. Hands-on materials and a steady routine help them build independence one small success at a time.
3 – 6 years3 – 6 years
Preschool
Ages 3 to 6 dive into the full 5-area Montessori curriculum: practical life, sensorial, language, math, and cultural studies. Your child learns by doing, not by sitting still and listening.

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.”
“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.”
“Both of our boys started in the infant room and stayed through pre-K. Four years in, it still feels like family.”
“Real Montessori materials, real patience. Our son reads now and nobody ever sat him down and made him.”
