St. John's Northwestern Military Academy

St. John's Northwestern Military Academy (SJNMA) was founded in 1884 as St. John's Military Academy (SJMA) in Delafield, Wisconsin, by Rev. Sidney T. Smythe as a private, all-male college preparatory and leadership development school. In 1995, St. John's Military Academy merged with Northwestern Military and Naval Academy (NMNA) in Lake Geneva, Wisconsin, to become St. John's Northwestern Military Academy on the Delafield campus.

SJNMA is principally a boarding school for students in grades 7-12, but also has an active day program and a one-year post-high school program that is conducted in partnership with the University of Wisconsin System with tailored instruction delivered at a college level. The Academy also offers several summer programs including four one-week, high-energy adventure camps, a five-week Summer OPS academic program and an English as a Second Language program.
