What is MMCI?

Monocacy Montessori Communities, Inc. (MMCI) is a local, volunteer-driven, 501(c)(3) nonprofit organization that manages two Frederick County public Montessori charter schools – Carroll Creek Montessori, opened in fall 2012, and Monocacy Valley Montessori, opened in fall 2002. Our schools are open to all children that live in Frederick County, and begin with Pre-K at age 3.


The mission of Monocacy Montessori Communities is to provide all children in Frederick County access to a high quality Montessori education that is free of charge through the establishment and management of public Montessori charter schools.

Carroll Creek Montessori, MMCI’s newest charter school, opened in fall 2012. CCMPCS has three classrooms at the Primary (age 3- Kindergarten), Lower Elementary (Grades 1-3) levels, and Upper Elementary (Grades 4-6) levels. CCMPCS will open one Middle School (Grade 7) classroom in the 2016-2017 school year. CCMPCS will continue to add a grade level with each year of matriculation until reaching capacity of PreK3 through Grade 8.

Monocacy Valley Montessori is the first charter school in Frederick County, and the first charter school in the state of Maryland. Opened in fall 2002 with 180 students, Monocacy Valley Montessori now serves 300 children annually from pre-k3 through 8th grade.
