Campus & Facilities

Our 36-acre campus is located on the Brookline-Boston line. We are just miles from Boston's best museums, libraries, hospitals, colleges, and universities – all of which serve as an extension of our classrooms.

The Clay Center for Science and Technology is a state-of-the-art astronomical observatory and learning center located on campus. In addition to the observatory's seven research-grade telescopes, this five-story building contains sophisticated computer and science labs, a multimedia lecture hall, classrooms, campus dining, meeting spaces, and a solar roof deck. Students in all grade divisons take advantage of this resource.

Multiple athletic facilities include: an indoor swimming pool, two ice rinks, indoor tennis courts, two turf fields, baseball and softball fields. The School also has a Rowing Center, located on the Charles River just four miles away in Dedham.

The Playscape, located in the woods behind the Arts Center courtyard, was designed to promote imaginative and creative play, to help connect students to nature, and to integrate play with the science curriculum. It combines landscape elements, forts, sand boxes, climbing structures, waterscapes, gardens, music, art and natural materials.



Transportation to and from the School is provided by our fleet of faculty-driven school buses from central locations throughout Greater Boston, Metro-West, and the South Shore. The bus is a hallmark of the Dexter Southfield experience; students and parents get to know their bus stop "family," and feel comfort when the driver pulls up each morning with a smile and friendly "hello."
