Toward the end of the 1950s a movement to provide better education opportunities for the Catholic high school age students resulted in a number of consolidations in the Dubuque Archdioceses.

On July 3, 1956, pastors of the parishes surrounding St. Joseph's, Bellevue, held a preliminary meeting to discuss the concept of a central Catholic high school to be opened in the fall of 1957.

Overseeing the corporation were Archbishop Leo Binz, Monsignor George Biskup as Archdiocesan Vicar General, Father Frederick C. Bahning as Executive Coordinator and two laity Matthew Manders of Bellevue and Reinhold Steines, Sr. of Springbrook.

Archbishop Leo Binz dedicated and blessed Marquette Catholic School before a large crowd of parishioners, students, and local dignitaries on October 27, 1957.

The first faculty of Marquette Catholic School was composed of Archdiocesan priests and the Franciscan Sisters of Perpetual Adoration of La Crosse, Wisconsin.

As a result, enrollment at Marquette Catholic School increased to 266 and two lay teachers and three religious sisters were added to the faculty.

The new center also features an ICN - Iowa Communications Network room that allows students to attend college accredited courses via video conferencing.

Construction included the addition of a multipurpose room and "parish center" where Fifth Street once existed, connecting all campus buildings excluding the church.
