Some History...
In the late 1800s, several prominent people of the Archdiocese of Philadelphia began to discuss the need for a school to educate women of the Delaware Valley. Father (later Bishop) McDevitt and Mrs. Mary McMichan were the leaders in founding five "High School Centres" in 1901 which paved the way for the building of Catholic Girls High School in 1911. Upon the death of Mary McMichan, the name of the school was changed to John W. Hallahan Catholic Girls High School in honor of her brother, as she requested. Over thirty-seven thousand young women have earned diplomas and have dedicated their talents and lives to society in such callings as mothers, medical professionals, educators and business executives throughout the nation and the world.
