History
St. Brendan first opened along Western Avenue between Second and Third Streets in the year 1915, staffed by the Sisters of the Immaculate Heart. In 1927, the Sisters of Charity of the Blessed Virgin Mary (BVMs) replaced the Sisters of the Immaculate Heart. In 1988, the administration of the school was assumed by a Sister of Saint Joseph of Carondelet and that continued until June 2018. Since 1988, the charism of the Sisters of Saint Joseph of Carondelet—Unity and Reconciliation—has permeated the school through the spirit of the documents and traditions, as well as the day-to-day operations.​
In 1960, the school building on Western Avenue was demolished because of safety concerns, and a new school building was constructed on the opposite side of the school yard facing Manhattan Place. Saint Brendan School currently consists of three large buildings: two classroom buildings and the Fleming Family Center. The south building includes homerooms for first through sixth grades, as well as the main office, staff work rooms, computer lab, music room, art room and library. The transitional kindergarten classroom, kindergarten classroom, science lab, middle school art room, history room and seventh through eighth grade homerooms occupy the north building. ​
The Fleming Family Center is used as both an auditorium and gym and includes an industrial kitchen which is used for student lunches and special events on campus. The center also hosts Saint Brendan Basketball Association (SBBA) and Goldie’s Youth Sports, neighborhood recreational basketball leagues. Through these leagues Saint Brendan School’s physical plant addresses the needs of our school community and the surrounding community. Both leagues are hugely popular and a great boon for our school.
​
Saint Brendan School has undergone various plant improvements since 2017 including installations of SMART Boards in 2020, renovations to the four bathrooms in the south building in 2022, and installation of turf on the Gus Deppe Memorial Field in spring of 2023. Most recently, a new transitional kindergarten classroom with bathrooms was constructed in the summer of 2023.
