History

In July 3, 1951 Father Gerald J. Morrissey was commissioned by Cardinal Stritch to form a new parish in the rapidly growing southern section of La Grange and Western Springs. The 440 Catholic families in this territory were being served by St. Francis Xavier Parish. After months of survey, a site for the parish was chosen on the north side of 55th Street between Spring and Stone Avenues. The new parish was canonically erected by the Cardinal Archbishop on October 5, 1951 under the title and patronage of St. Cletus, Pope and Martyr.

The first building, designed by Mr. Thomas E. Cooke, A.I.A., consisted of a temporary church seating 450 people and two wings containing eight classrooms, a kindergarten, music rooms, and administrative offices. A convent was located on the second floor over the school. St. Cletus School opened in September 1953 with 412 students enrolled in kindergarten through seventh grade. Eight grade was added the following year and the first class was graduated in June, 1955. The Sisters of St. Joseph of La Grange have staffed the school from the beginning with Sister Mary Wilfrid serving as the first principal, until the Sisters were no longer able to staff our school any longer, in 1985.

The initial building was dedicated by Cardinal Stritch on April 24, 1954. Plans for the permanent church and rectory were drawn up, and ground was broken in July 1960 for the new church.
