History
St. Brendan Parish is named after St. Brendan, the legendary navigator and one of Ireland's beloved saints. It is under this patronage that the school enjoys being "Irish" and celebrates its uniqueness as a Catholic institution of learning.
St. Brendan School was opened in August, 1921, with 40 students. The Sisters of the Most Precious Blood from O'Fallon served the parochial school until 1980. In 1987, the School Sisters of Notre Dame from the St. Louis Province began to serve the school and remained for the next 12 years. In 1999, St. Brendan saw the end of female religous serving the school.
St. Brendan High School opened in 1925, providing an alternative to secondary education until it closed in 1959. The school was housed in the bottom levels of the current building with the church on the top floor. In 1943, a convent was built next to the school, and in 1957, a new church and rectory were added to the parish property. Classrooms were added to the original chuch space. Completion of the multipurpose building adjacent to the school was accomplished in 1980. In 1989, a commercial kitchen was installed in the parish center and the lunchroom was moved from the basement level of the school to the gymnasium. Within the next three years a computer room, science lab, and office space were added to the school.
Current enrollment is for grades 3 year old Pre-K thru 8th grade.
