History and Campus

History Text
Lexington Montessori School was founded in 1963 by a group of parents seeking a child-centered education for young children. Based upon the philosophy of Maria Montessori, LMS has grown over the years from a small preschool to a nationally recognized leader in Montessori early childhood, elementary and middle school education. LMS currently welcomes over 230 children from a wide range of towns and communities in and around the Boston area.
Our school continues to evolve and grow; our campus is a vibrant, thriving and welcoming community for our students, teachers, parents and alumni families.
Our campus is comprised of four separate buildings: the Children’s House, the Jane Mack Elementary Building, No. 10 and No. 12 Lawrence Lane.

For many of our students, the LMS campus is their first community outside of their families. The Children's House is home to Toddlers through Kindergarten. The Head of School, Admission Office, the Director of Faculty and Curriculum Development and the Main Office are all located on the second floor of this building.

The Jane Mack Elementary Building was named after the school’s founder and former Head of School. Lower Elementary students, grades one through three, and Upper Elementary students, grades four through six, as well as the multipurpose room, Spanish classroom, our Learning Specialist and the Before and After School Program are all located in the Jane Mack Building.

No. 10 Lawrence Lane houses Music and Art classrooms, the Library, and our Middle School.

No. 12 Lawrence Lane is currently used for administrative offices including Community Development, Business, Technology and Facilities. 

Green space is important at LMS. Our children enjoy time outdoors most days of the year. Preschoolers run in the grassy oval, and climb on play structures directly behind the Children’s House. Elementary and Middle School students use the Upper Field behind the Jane Mack Building for free play and field sports during gym. Surrounded by woods and nature paths, the Upper Field also contains a climbing structure appropriate for older children.
