Since its inception 1934, the Dillon Child Study Center has focused on the individuality of each child and the importance of the early childhood years in a young child’s development. A successful combination of innovative programs and caring staff from the start, Dillon is aware of the evolving needs of children, parents and professionals.

We work to develop a child who is a lifelong learner, and to foster and enhance the natural curiosity in all children. We see school as a place to grow and wonder. We value children’s natural ability to play as a crucial tool for their growth and learning.

“These teachers made my child feel loved and happy to go to school each day.”

- Classroom 2 Parent

Dillon has been such a sweet, magical experience for Zian.  It’s the first place that he has readily wanted to leave me to “go to big boy school” and just this past week, it’s the place that inspired a meltdown when he found out he was on “break.” He adores his teachers and his confidence as a learner has grown in leaps and bounds.  When we drive by it, he declares so proudly that it is “[his] school.”

“Classroom 4 and its teachers are phenomenal. What a loving and supportive environment it is & such a tremendous asset for St. Joe’s.”

- Classroom 4 Parent

I love the Dillon Center and the gentle, nurturing environment with spacious classrooms and a beautiful outdoor play area. The thing I love most about the school is the warmth and genuine love from all the teachers I have gotten to know over the years. They are all so passionate and kind, giving honest feedback on the kids and also explaining developmental stages in a non-judgmental way.

The children in Sister Pat’s class have bonded very well. They are like a little family. It’s a wonderful and nurturing environment. I am so happy that my son has continued on for one more year at Dillon.


Dillon has a beautiful outdoor play area for its pre-schoolers. The staff at Dillon ROCK!!!


My son absolutely loves going to school! He is learning how to be a flexible thinker, a curious investigator, a thoughtful problem-solver and a lover of life! And somehow the teachers make it all seem so effortless. Dillon is a wonderful community of educators who really care about teaching the whole child, we are thrilled to be a part of it!

- Classroom 3 Parent

“Our son has flourished at Dillon-first in Classroom 1 and now is having a fantastic year in Classroom 5. He is one of the younger children in the class and we have watched him grow in confidence and develop fantastic friendships attending Dillon. There are excellent facilities and it is a beautiful and secure setting for children. In short, at Dillon they really support and see the whole child.”

- Classroom 5 Parent

“Our daughter’s enthusiasm and excitement for going to school every day is a testament to the incredibly caring, creative, nurturing, patient, and supportive Inclusion teachers. It has been remarkable, as parents of a special needs child, to watch her grow and we give tremendous credit to Dillon.”
