Since 1995, Keystone Montessori in Ahwatukee has been offering its students a Montessori education.

Keystone Montessori began with an enrollment of 13 students from ages 3-6 inside founder Sherri Sampson’s living room.

The school’s facility moved from Sampson’s living room to Horizon Presbyterian Church, which assisted the church on building its educational wing, and in 2000 the school moved to its current location on Liberty Lane.

In 1995, the elementary program at Keystone Montessori became charter certified, so the school could educate as many students as possible.

Currently, the school houses 320 students from 18 months old to ninth grade.

Cindy Maschoff, assistant head of school, said the initial expansion of grade levels wasn’t always the primary goal, but the school wanted to help support the community need for Montessori.

“We believe that we are a full-spectrum school, so we have that large age group… we also have a long-standing staff who are a group of committed educators,” Maschoff said.
