A LEGACY OF STRUCTURE, SINCE 1884

For over 140 years, St. John's Northwestern has built its reputation on one idea: every student deserves a foundation for life, not just a diploma. Our historic Delafield campus gives students a 12-to-1 student-teacher ratio, supervised evening study halls with peer and tutor support, and secure residence halls — all about an hour from Madison, close enough for regular visits, far enough to build real independence.

For Madison-area families, SJN offers a Wisconsin-based alternative to out-of-state boarding schools — the same level of structure and college prep, without leaving the state.
