Who we are
The Frederick Gunn School, founded in 1850, is a coed boarding and day school for 330 students in grades 9-12 as well as a post-graduate year located in Washington, Connecticut. Frederick Gunn was a pioneering educator, courageous abolitionist, and rugged outdoorsman. He inspired generations of students to be curious and thoughtful, to be active members of their communities, and to stand up for what they believe in. He was a transformational leader with an educational philosophy that shaped the foundation of our school. This vision is even more powerful today as our students become principled, active citizens and lifelong learners, who will be entrepreneurial forces for good in the world.
We are highlanders.
Hear from students, teachers, and alumni who are living the mission — who are learning boldly, leading kindly, and leaving their mark on the world. At Gunn, every voice adds to our legacy of purpose.
