Saint Thomas Aquinas Academy is proud to be part of the rich Catholic teaching tradition that has been in northeast Wisconsin since 1876.  We have the privilege of making faith the cornerstone of all we offer to our students and families.

The Pre-K through 5th grade Elementary campus is located in Peshtigo at St. Mary Parish.  The Middle and High school campus is located in Marinette.  Our caring and dedicated faculty work to meet each students needs in a safe and encouraging environment.  Each day begins with prayer and all students attend and participate in Mass weekly.  Our students benefit from a low student to teacher ration and highly individualized attention in the classroom at all levels.  Strong academics, fine arts, extracurricular and service activities, and athletics combine to give students opportunities to reach their highest potential.  We welcome students from all backgrounds at the Academy.  We invite you to discover the difference that the gift of faith makes in education!
