On Explorers!

Learn what being an Explorer is all about

Founded in 1927, Marquette Catholic High School is a college preparatory,
co-educational school where we do exactly that, prepare students for college.

It's a great time to be an Explorer!

The Marquette experience is unique, challenging and - a lot of fun. Every year, our students go on to attend some of the nation's finest universities. As a college prep school, we prepare our students to graduate from, not just get into, college. We know we have succeeded when our graduates tell us "Marquette was tougher than their first couple years of college."
Our graduates also become a part of the Marquette family for life.  If you are a prospective student or the parent of a prospective student, we hope you will come to visit us and learn what being an Explorer is all about.
