The Northwest School was founded in 1980 by Ellen Taussig, Paul Raymond, and Mark Terry.
Alongside the historic Summit School building and the school's dormitory for boarding students, modern additions to the Northwest campus were completed in 2006 (expanded photography studio, library, and computer lab) and 2014 (gymnasium, fitness mezzanine, dining room, kitchen, black-box theater and a roof-top sports field) [REF].
