Shrewsbury Montessori School (SMS), previously The Montessori Center of Shrewsbury, was founded forty-five years ago when Mrs. Nancy Corkum began her mission to bring Dr. Maria Montessori’s educational philosophy to children in Massachusetts, first in Dudley, Auburn, and then in Shrewsbury, Massachusetts.

In 1972, Mrs. Nancy Corkum opened her first proprietary school, Treetops, in Dudley, Massachusetts. Initially Treetops consisted of the youngest Corkum son, four preschool classmates, Mrs. Corkum as the Lead Teacher, and one Assistant Teacher. To accommodate the increasing enrollment between 1976 and 1981, she established the Children’s House (CH) in Auburn, and classrooms located at the Fay School in Southborough, the Beal School, Shrewsbury, and Mt. Olivet Church in Shrewsbury. In 1986, Nancy and Keith Corkum purchased the property at 55 Oak Street, Shrewsbury, establishing the Montessori Center of Shrewsbury, Inc. Six classrooms were added to the house. Two additional classrooms were added in 1989. The All Purpose Room (AP Room) and the Media Center/library/language classroom were built in 1998.

In the fall of 2004, Mrs. Corkum announced her retirement and her intention to sell the School. A group of parents offered to help convert the School to a not-for-profit 501(C)(3) organization. The parent group raised the necessary funds, secured a mortgage, and established the bylaws of the corporation. The SMS faculty continued in their roles through this transition.

In January 2005 an Interim Head of School was hired. The first permanent Head of School was hired in July of 2007. The Shrewsbury Montessori School is a nonprofit, independent institution with three campuses: Auburn, Worcester, and Shrewsbury. Although staff, campus facilities, and playgrounds have changed over time, the commitment to providing a strong Montessori education to children, as first envisioned by Mrs. Nancy Corkum, remains. Shrewsbury Montessori School is accredited by the Association of Independent Schools of New England and the American Montessori Society.
