About Dexter Southfield   Dexter Southfield is an independent school where boys and girls in Pre-K through Class 12 develop their individual talents and build an ethical foundation for life. Through a classical education and innovative programming, students learn to lead with confidence and serve with compassion. Our 36-acre campus is located on the Brookline-Boston line, just minutes from the city’s best museums, libraries, hospitals, performing arts venues, colleges, and universities—all of which serve as an extension of our classrooms.
