About Us

Our Facility

We moved into our Passiv House-standard building in 2017. Designed and built by Belfast-based architecture and construction firm GO Logic, the new facility is highly energy efficient and green, with photovoltaic panels supplying the majority of our electricity. Just minutes from downtown Belfast but situated on more than 35 acres of woodlands, Cornerspring offers a wealth of opportunities for nature-based education.

Our History

Cornerspring Montessori School was founded in 2001 by Paula Johnson in response to a need in the area for a high-quality preschool program. Originally located in a Victorian home in downtown Belfast with an enrollment of eight children, the school’s reputation and the appeal of Dr. Maria Montessori’s teaching philosophy grew and enrollment increased.

In 2007, Cornerspring became a non-profit institution, and in 2008, in order to meet the needs of its growing community, Cornerspring added an elementary program and moved to the athenahealth campus on Route 3. 

A few years later, in 2012, the Board of Directors conducted a strategic planning process to identify a new, permanent home. During a yearlong search, the committee reviewed 40 potential buildings and sites, and ultimately recommended building a 6100 sq. ft. school on a wooded property on Lower Congress Street. In the fall of 2014 the board approved the purchase of 35 acres and a building design by GO Logic, an architecture and construction firm based in Belfast, Maine that creates sustainable, super-insulated, highly energy-efficient buildings. Ground was broken in the Fall of 2016 and the community moved into the new building in July of 2017.

Today, Cornerspring is recognized as offering families an outstanding choice for children ages 18 months to 12 years in a beautiful natural setting.

Mission Statement

Using an approach based in the methods developed by educational visionary Maria Montessori, Cornerspring Montessori School is committed to individualized education, allowing children freedom to develop at their own pace. We strive to satisfy a child’s need to know, to belong, to feel safe and secure, and to develop their self-esteem. Our nurturing staff is Montessori-trained, and our school accepts all children as individuals and does not discriminate in any way based on race, ethnic background, gender, disability, or financial position.

“Let the children be free; let them run outside when it is raining; and when the grass of the meadows is wet with dew, let them run on it and trample it with their bare feet; let them rest peacefully when a tree invites them to sleep beneath its shade; let them shout and laugh when the sun wakes them in the morning.” – Maria Montessori
