Merrimack Montessori School was first opened in 1965 offering Pre-School and Kindergarten by the Sisters of St. Joseph of Boston. Merrimack Montessori is one the earliest Montessori Schools opened in the United States and today remains one of the oldest continuously operating in its original building. Our beautiful location was once a
private home, built in the 1920’s and next a Jesuit Boy’s School and then became a pre-school at the time when Montessori was just becoming popular in Massachusetts. The Sisters of St. Joseph were the schools first teachers and leaders changing over time to all lay faculty and administration. The school is governed by a non-parent board with alumni, alumni parents, and local business people from the community and the Sisters of St. Joseph serving as board members.

Merrimack Montessori is one of nine ministries that are sponsored by the Sisters of St. Joseph of Boston. MMS attracts families of many faiths and as part of the school’s mission we are committed to addressing the social, educational, and spiritual needs of each child, teaching them respect, fostering joy and peace, and love of all living creatures. Our faculty is committed to creating experiences for young children that guide their moral and spiritual development toward values such as love of neighbor, unity, justice, compassion, courage and an appreciation of diversity.
