About St. John’s Northwestern

Preparing young men and women for college and a lifetime of opportunity

Who We Are

Since 1884, St. John’s Northwestern has prepared young men and women for college and a lifetime of opportunity. Nestled in the center of beautiful Delafield, Wisconsin, we are principally a boarding school for grades 7-12. For those living in the neighboring towns, there is also an active day student program. Academic excellence is at the center of the St. John’s Northwestern experience.

St. John’s Northwestern has followed a format for the benefit of structure, and the advancement of honor, dignity, and respect. While many graduates have been admitted to the five military service academies, the majority advance to notable colleges and universities around the world.
