Originally known as St. Mary's Training School for Boys, the facility was the vision of Chicago archbishop Patrick A. Feehan and served as an orphanage for many decades.
Following a rebuild after a massive fire in 1899, St. Mary's new director, Reverend James Doran, opened the facility to girls in an effort to reunite orphaned brothers and sisters.
[1] The appointment in 1970 of Father John P. Smyth, a former all-American basketball player at the University of Notre Dame, as director was significant, as he overhauled the way Maryville was managed, reducing costs and changing the facility to a more home-like setting that was conducive to the facility's newly acquired role as a home for children who experienced trauma and neglect.
Subsequently, the State of Illinois removed residents from the facility, a move which almost resulted in Maryville being permanently closed.
Maryville operates six service areas,[clarification needed] with campuses in Bartlett, Chicago, and Des Plaines.
