The frederick gunn school cultivates independent critical thinkers empowered to be a force for good. We educate highlanders to be ambitious citizens who are always learning and courageous in character like our founders frederick and abigail gunn.
In 1850 frederick gunn established a school based on the belief that strength of character was the goal of education. Today, the gunnery rests on the four cornerstones of character: scholarship, integrity, respect and responsibilty. Character is forged in a cohesive, diverse community informed by a challenging college preparatory curriculum, a broad range of athletic, artistic and social activities and a faculty of scholars and committed educators dedicated to the intellectual and ethical development of every student. A gunnery graduate is a broadly educated, socially responsible citizen with tested beliefs, strength of character and the courage to act on convictions.
