So happy with this school! A great fit for any learning style, with experienced teachers who love their job. We love the special balance of a child centered, nurturing environment with excellent academic preparation.

We are so satisified with our decision to place our children at Woodside Montessori Academy. The kids are exposed to such a great variety of subject matter that they would not typically be learning in a public elementary school, especially not at their grade level. For example, our first grader is already learning about astronomy, geometry, geology, geography and more! This is accomplished all while still following the Massachusetts required curriculum. We highly recommend this school!
