St. Mary School is celebrating its 75th anniversary. When it opened its doors three-quarters of a century ago, Harry Truman was in the White House, the New York Yankees were World Series Champions (some things are timeless), and the Diocese of Joliet was one year old.
Let’s step back in time and explore how St. Mary School has grown throughout the decades.
Location, Location, Location
The first St. Mary School was located in a wooden frame building that stood opposite the old church on Wolf Road (on the current parking lot site). This same building had served as the parish hall since its construction in 1926. It consisted of three classrooms and a basement. Due to the lack of space, different grade levels had to share rooms.


To meet growing population needs, the parish broke ground for a new school and church building on the current site on 195th Street and 115th Avenue. It opened in November 1955 and expanded 10 years later in 1964, when there were roughly 400 students.

In these early years, the parish owned its own school bus, and the pastor, Fr. Cecil Koop, drove it daily. Mary Frances Consola, who was a student during the 1950s, recalls Fr. Koop picking her up from her home in Orland Park, as well as driving students on field trips, including to Springfield, IL.

In 1962, the men of the parish built a garage to house the school bus and serve as a gymnasium and events center. Bishop Romeo Blanchette nicknamed this garage the “Cow Palace,” comparing it to the Cow Palace Convention Center in California.


St. Mary Parish and School continued to thrive. To accommodate the explosive growth, the parish tore down the “Cow Palace” to make room for the current church building in 1987. At this time, the parish also converted the old church into the school gymnasium.



By the late 1990s, it was once again time for a major school expansion. After a successful capital campaign in 2003, the parish undertook an eight-million-dollar project that added a new gymnasium, cafeteria, music room, art room, and science lab to the school, in addition to six new classrooms. In 2008, the old gym was converted into the Koop Library and Media Center.

Since then, the school has continued to make incremental improvements at its current location, including the addition of a preschool classroom, an updated library, and a STEAM Lab.
Life at St. Mary School
Buildings are important, but they are nothing without the generations of students and teachers who have walked through them.
The Teachers
For decades, St. Mary was primarily staffed by the Franciscan Sisters of the Sacred Heart. Mary Frances Consola, who graduated in 1960, recalls that the nuns taught arithmetic, grammar, spelling, history, and, in those days, the Baltimore Catechism. During that era, students attended Mass daily and said prayers multiple times each day.

She also recalls some creative discipline methods, in particular one used by Sr. Helen Ann. Each time Sister told the class to be quiet, she would write a number on the board. At the end of the day, the number on the board was how many times the students would have to write out their multiplication tables. Consola admits that, after writing them out so much, her class got good enough at their multiplication tables to beat the older kids in a multiplication competition!
Although teaching and disciplinary methods changed throughout the years, the sisters always took their vocations seriously. For example, Sr. Kathleen Hook used her musical passion to train student choirs and play the church organ for school Masses. Sr. Mary Jane Sola taught reading to first graders for decades. Sr. Mary Benedict was a beloved art teacher who had a silk screen press.

In total, 58 Franciscan sisters served at St. Mary parish between 1949 and 1999, when the last three left their positions. At that point, lay teachers, who had taught alongside the nuns for decades, continued the legacy of excellence.
Among them was Mrs. Gloria Janousek, who proved instrumental in founding the school’s computer program in 1994. “St. Mary School was definitely one of the pioneers in the area and the diocese in technology,” explains Janousek. “We were one of the first schools with a computer lab.”

The computer program instilled the foundational technical skills that many students now apply daily in the workplace as adults. Mrs. Janousek continued to grow the technology program until her retirement in 2022, spearheading the use of tablets in the classroom and the creation of a STEAM (Science, Technology, Engineering, Art, and Math) program.
Longtime physical education teacher, Mrs. Anne Lindley, also left a permanent mark on the school, instilling a foundation of fitness in countless students. Among her contributions were the Jump Rope for Heart Program, which raised money for the American Heart Association, the launch of a cup stacking tournament, and yearly physical fitness testing.
Besides these, Lindley introduced generations of students to a variety of athletics, from roller skating to volleyball, to pickleball (before it became popular).

Students Then & Now
No matter which decade or in which building, St. Mary alumni have fond memories from their time as students.
…Eating hot lunch pizzas, picking up milk cartons for the class, raising the flag in the morning, walking to school Mass, waiting for the bus, learning to type with orange keyboard “skins,” competing against other schools in the end-of-year-olympics, writing and exchanging Valentines during the classroom Valentine’s day party, playing hockey in the “Cow Palace,” joining the basketball team, learning to read from the “On a Blue Hill” textbook, memorizing multiplication tables, walking to recess at Willowview Park, playing “crab soccer” in gym class, dancing at graduation banquets…
All are different memories, yet many are shared by entire classes of students. Some are shared by nearly every student who ever attended the school.




Although years and decades divide them, there is something timeless that unites all St. Mary School students and alumni. They were all children in the dawn of their lives. St. Mary provided them with some of their earliest and most formative memories, lessons, and experiences that have remained with them throughout the years.
To all the teachers, staffmembers, volunteers, clergy, and parents who have made this possible for the past 75 years, thank you.
