OUR TEAM

The Heart of The Cornerstone School. We invite you to meet the team of educators and staff who bring the Cornerstone mission to life every day, guiding, supporting, and inspiring our students from toddlerhood through adolescence. As a proud member of the American Montessori Society (AMS), Cornerstone is staffed by dedicated professionals, many of whom hold one or more levels of Montessori certification.

Each classroom at Cornerstone is guided by two Montessori-trained teachers, giving children the benefit of close attention and a variety of teaching styles. What truly sets our faculty apart, though, is not just their training—it’s their genuine love of helping students grow. They nurture curiosity, encourage independence, and create a supportive atmosphere where every child feels seen and inspired to do their best.

At Cornerstone, our educators are more than teachers—they are mentors, role models, and champions of each child’s journey. Their expertise, compassion, and commitment form the true heart of our school community.
