Delaware’s only boarding school was founded in 1929, and has been co-educational since 1974. The school is committed to seminar classes, advising and mentoring and wide opportunities in the arts, athletics and community service. All faculty live on campus. “This gives students the opportunity to work intensively and collaboratively with their teachers morning, noon and night,” says headmaster Tad Roach.
