In the summer of 1996, a group of 6 families from the Lone Tree and Castle Rock Montessori school communities came together with a goal to develop a charter Montessori elementary school. Soon they were joined by dozens of other families with a similar interest and, after months of tireless efforts, they received a charter from the Douglas County School District in March of 1997. In this same year, the MEF obtained non-profit status and the school began educating our children in a temporary modular building.

A few years later, MEF parent volunteers secured a 7,000,000 bond to finance the permanent elementary school facility. The current facility opened in the fall of 2000.

Contributions to our non-profit entity are tax deductible and are used solely for the benefit of DCS Montessori School at the direction of the DCS Administration and the DCS Board of Directors.
