At Denison Montessori, we have a passionate, dedicated staff who are committed to helping each child realize their full potential through the Montessori Method.  They use the Montessori curriculum and materials to work with the whole child, helping the child move towards independence and become a life-long learner.

The staff is highly accomplished and all hold either AMI or AMS Montessori teaching credentials.  Many of our teachers also hold advanced degrees or multiple Montessori credentials.
