Imagine what is possible when your classrooms are filled with the most brilliant and dedicated of teachers. At Derryfield, each and every one of our 52 faculty members strives to inspire students to think differently and challenge themselves. They encourage discussion and debate. Their roles seldom stop at teacher: they are mentors, advisors, and coaches. Coupled with an average class size of 15 students, it is our collaborative student-teacher relationships that are the hallmark of a Derryfield education.
