The school at St. Monica Parish was founded by its first pastor, Father George Stuebben, and began accepting pupils in the fall of 1960. Two surplus military barracks buildings were purchased from Ft. Sam Houston, moved from the post to the parish grounds and modified for teaching grades one through eight. Sister Michael Ann, its first principal, assisted by Sisters Damian and Florence were among the original staff and were from a community called the Sisters of the Missionary Servants of St. Anthony. In 1966 a group of Franciscan sisters assumed the responsibility of educating the children and taught for four years prior to returning to their community. At or about this time all subsidy from the parish ended and it appeared that the school would have to close. Unshaken by this possibility, the school board which included Mr. William Sparks, Mrs. Ellie Opdycke and Mr. James Hickey devised a plan to keep the school open. School year 1970/71 was a new beginning with only two grades, kindergarten and first. Over the next ten years the school would experience moderate growth.

In January 1983 Mr. James Mollicone assumed responsibility for the school program. By this time the converted barracks were deteriorating rapidly and were becoming a financial burden to maintain. Enrollment was approximately 170 students in grades preschool through fourth. Also a small day care and summer activity program were in effect. The school board, after several unsuccessful attempts to acquire the support and resources necessary to rebuild, authorized Mr. Mollicone to begin a development program and plan for the construction of a new school. By 1986 enrollment was up 60%, day care users had increased 300% and the summer activity program had quadrupled. This growth allowed the school to increase teachers' salaries and accumulate over $100,000.00 for its development fund without increasing tuition. By late 1986 the development fund had grown to over $200,000.00 thanks to the generosity of teachers, parishioners, and individuals from other parishes who had enrolled their children in St. Monica School. With the full support of its pastor, Rev. Msgr. Patrick Flanagan, the archdiocesan finance committee was given a briefing on replacing the school. It was also advised that the entire development fund was available for a down payment and that permission to build was now a necessity. Archbishop Patrick Flores subsequently approved the request and in the summer of 1988 a new education center was dedicated.
