Brunswick School was founded in 1902 by George B. Carmichael, a teacher at the nearby Greenwich Academy. The school is a college preparatory day school serving approximately 930 boys in grades pre-kindergarten through 12.
Brunswick school is made up of two main campuses. The Upper School campus is located on Maher Avenue in Greenwich. The Upper School English and history annex is located on North Maple Avenue, a short walk from the main Upper School facility, and sharing a building with the Preschool. Also found at the North Maple facility is the Brunswick Career Center, which puts an emphasis on preparing recent alumni for the workforce. The Edwards Campus (named after former headmaster Duncan Edwards, II) is located about 15 minutes away from the Maher Avenue campus on King Street. The Edwards Campus is made up of the Lower School and Middle School facilities, along with the Burke Fieldhouse (basketball, wrestling, tennis, and the Cosby Weight Room) and Sampson Fieldhouse (which houses the Dann O'Neil Gym, the Stephens Squash Courts, and Hartong Rink). A facility dedicated to science and arts for Upper School students is also located on the Edwards Campus. Additionally, Brunswick owns a boat house located on River Road, just a twenty-minute drive from the Upper School campus. Brunswick recently purchased a property in Vermont which will house specially designed programs for underclassmen boys to attend for a few days out of the school year.

Coordination with Greenwich AcademyEdit
Brunswick's sister school is Greenwich Academy, which is located two blocks from Brunswick's Upper School campus. The two schools share classes with each other during Upper School, and students are able to choose courses from a combined course catalogue, with the exception of mathematics courses and ninth grade English, which remain separate. The connection between ""Greenwich Academy"" and Brunswick dates back to the school's founding. The founder of Brunswick had been previously employed as a teacher at Greenwich Academy, which was then a co-educational secondary school. After the founding of Brunswick, Greenwich Academy began admitting girls alone, directing boys to apply to Brunswick School.
