Welcome to 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.

Carroll Creek Montessori, MMCI’s newest charter school, opened in fall 2012 and currently serves 130 students in grades pre-k3 through 3rd grade. Carroll Creek Montessori offers students a Spanish language immersion program and a Spanish language enrichment program, in addition to a Montessori education.

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.

Due to the popularity of both of MMCI’s charter schools, admission to join either school is through a lottery. Please visit our lottery page for more information about the lottery process.

Mission: 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.
