Holy Cross Heritage

Our History

Holy Trinity was founded by the Brothers of Holy Cross in 1910 to educate the growing number of children of Polish immigrants who settled on the near-north side of Chicago. Holy Trinity is the second oldest high school ministry of the Congregation of Holy Cross in the United States.

As the neighborhood around the school changed, Holy Trinity High School made a conscious decision to continue welcoming local youth, many of whom represented new groups of immigrants. Unlike other schools that had been in the area and moved out, Holy Trinity has provided more than a century of continuous service to the youth of Chicago. In 1984, after a lengthy study and with the cooperation of the Archdiocese of Chicago, Holy Trinity High School added young women to the student body. Today, in keeping with the spiritual tradition of the Brothers and the educational framework of their founder, Blessed Fr. Basil Moreau, C.S.C., we continue to educate youth from across the city, recognizing the unique spirit of all students and challenging them to realize their potential.

As a member of the Midwest Province of the Brothers of Holy Cross, Holy Trinity is part of a supportive, worldwide community of educational institutions, including 16 high schools and eight colleges, including the University of Notre Dame.

Originally founded as a parish high school affiliated with Holy Trinity Parish, complete responsibility for the direction of the school was assumed by the Brothers of Holy Cross, Midwest Province, in 1960. Today, the responsibility is shared with a Board of Trustees composed of community leaders, graduates and other concerned persons who ensure ongoing development and enhancement of the unique Holy Cross educational traditions.
