Dexter Southfield School  The Dexter Southfield School is an independent co-educational day school located in Brookline, Massachusetts, educating students from pre-kindergarten through twelfth grade. Dexter Southfield was founded in 1926 as the Dexter School. In 2013 the Dexter School merged with the sister school Southfield School to form Dexter Southfield with which it had shared its campus since 1992. The Dexter School was founded in 1926 in response to the closure of the Noble & Greenough Lower School and lack of educational opportunities for boys in the Brookline area. The Dexter School opened on Freeman Street in the affluent Cottage Farm neighborhood educating boys through ninth grade. The school developed a strong bond with many of Boston’s leading families with ties to the leading preparatory and Ivy League schools. In 1966, Dexter sold its campus on Freeman Street and moved to their present location on a hill on Newton Street on the South Brookline/Jamaica Plain line. The school bought the property from the Catholic Foreign Mission Society of America who had resided on the site since 1945. The property was the former estate of Richard and Anna Sears, who had built a Mediterranean Revival Style villa on the site in 1928. As Dexter expanded, the school continued the style of the white stucco façade and red terra-cotta roof of the Sears House. Today, the original house remains the central structure on campus and houses the Senior Lounge, Business Office and Admissions Office. In preparation for the school’s move in 1968, the A building, Fisk Hall, and pool and gymnasium were built to the west of the Sears House. The Thorndike Hockey rink was added to the campus in 1973. From its long tradition as a boy’s lower school, Dexter has undergone a vast transformation over the last 25 years. In the 1990s, further additions were made to the campus including the construction of the Mid-Rise and original lower school building. In 1992, the Southfield School was established on the same campus to expand Dexter’s educational philosophy to young girls. In 2002, the Upper School was established to enable both the Dexter and Southfield schools to continue the school’s mission into the competitive secondary school market. The Clay Center was also constructed to the east of the Sears House greatly altering the school campus. The new center included a new auditorium, dining hall and fifth floor observatory. In 2011 Mr. and Mrs. William Phinney, who had led the school since 1964, and oversaw its move and expansion, retired after 47 years at the school.
