Founder, Director and Kindergarten Teacher

Since 1981, Terry Armstrong, Director of MMS, has believed there are three essential components of an authentic Montessori education: the right materials, the right teachers, and the Montessori philosophy. Under her leadership and teaching, Terry works everyday toward encouraging children to become caring and responsible people, and at the same time, making the school a happy and pleasant place to be.
