What Our
Community is Saying

I still think of the preposition as a green bridge. I still remember my lesson about avoiding dangling modifiers. I understand grammar rules and the construction of sentences because I sat for hours in Mr. Reveri’s class diagramming sentences.

Ande Isom, Alumni 1/4

An MMS education provides the warmth, strength, and academic rigor that have helped our son thrive academically. We are continually impressed by the work he is doing, while at the same time having fun! We love being part of the MMS family.

Luz and Tony Mack, Parent Elementary 3/4

Our children's education is personalized and adapted to their strengths and needs. We love having an ongoing dialogue with teachers about their progress and how to support their emotional development and academic success.
