Edgewood Seventh-day Adventist Elementary School is operated by the Stoneham Memorial Seventh-day Adventist Church. Other churches have special interest in the school, including the Boston Spanish Seventh-day Adventist Church, the Boston Temple, the Braintree Seventh-day Adventist Church, the Framingham Seventh-day Adventist Church, the Merrimack Valley Seventh-day Adventist Church, and the Waltham Seventh-day Adventist Church.

Edgewood had its beginning as the Stoneham Seventh-day Adventist School in one classroom on the grounds of the New England Sanitarium and Hospital in approximately 1927. In 1936 the school expanded to two classrooms and moved to the corner of Pond and Summer Streets as the church school for the newly formed Stoneham Church.

Enrollment continued to increase. In 1944 the Stoneham church purchased the old South School on Gerry Street from the Town of Stoneham. The four spacious classrooms were adequate until the expansion of New England Memorial Hospital in 1966-1969 brought many new Seventh-day Adventist families to the area.

Recognizing the need for larger quarters, the Stoneham and New England Memorial Hospital churches joined together to build the present school. The first full year in the new building at 108 Pond Street was 1970-71.

In 1975 the school took a new distinctive name: Edgewood School of Seventh-day Adventists. It stands as a memorial to the dedicated churches whose members believe in Christian Education.

In 2000 due to the closure of Boston Regional Medical Center and the loss of its facility on that campus, Greater Boston Academy joined Edgewood in the building at 108 Pond Street.
