School Overview

The High School Campus is a regional, comprehensive coeducational ministry serving the northeast Wisconsin and Upper Michigan Roman Catholic parishes and members of the surrounding communities for over 141 years.

This is accomplished by providing a strong academic curriculum and by engaging each student according to their unique strengths and abilities. Each day begins and ends with prayer. In addition, mass is celebrated weekly. Students, faculty, and staff form a community in which values are nurtured and translated into action. Students  participate in service projects that put their faith into practice.

In over 141 years, the Academy has had thousands of students graduates from the school.  Our alumni are a strong example of how our school (Saint Thomas Aquinas Academy, Catholic Central High School and Lourdes Academy) has prepared its students for the future.  A high percentage of students attend college after graduation and many have gone to Ivy League Schools, received appointments to West Point, Annapolis, and the Air Force Academy, attended Big 10 universities, and nationally recognized liberal arts colleges and universities.  Every year, our school is honored by graduates who choose military service through enlistment or ROTC.

The success of our alumni is unparalleled for a small community.  We have alumni that are national filmmakers, opera singers, scientists, entrepreneurs, surgeons, nurses, lawyers and politicians.  Our alumni have started or managed national companies, banking institutions, and continue to to build the area community.  Our graduates have served our country in times of peace and war, scaled Mt. Everest, trained for the Olympics, and gone on to become professors and teachers for the next generation.  Many graduates have been called to religious life and are now bringing the Catholic faith to others in the world.
