In September of the same year, the school separated from St. Paul's with Sister Canice Walsh, a Brigidine Sister who served as the first principal. The school comprised four classrooms and a temporary chapel. In 1960 enrollment reached 270, causing the construction of four additional classrooms and a cafeteria which was completed in 1963. Due to a continued increase in enrollment, another four classrooms were built in 1970. A gym was eventually added to the campus as well as temporary buildings in 1972 to house a library and a learning center. By the 1978-79 school year, enrollment reached 500 students. In 1988 the school underwent major construction which included extensive classroom renovations and the creation of a new middle school wing accommodating a new cafeteria, library composed of over 12,000 volumes, science laboratory, computer lab, and learning center.
