Marist opened its doors in September 1954, with Brother Leo Sylvius serving as the school's first principal. In 1962, the present campus was acquired to accommodate the school's growth after negotiations led by Brother Leo to acquire land owned by the City of Bayonne, and on April 23, 1964, ground was broken for a new building which would tie together existing buildings on the campus. A modern structure was constructed with 24 classrooms, lecture rooms and laboratories for physics, chemistry, biology and earth science, an art studio, a computer center, and a weight room. A library with a complete audio-visual department, a guidance complex with a career resource center, together with a large gymnasium-auditorium complex and cafeteria were also included as part of the new school building. In 1977, additional land was acquired for expanding the school's athletic facilities. In 1995, an athletic field was built in back of the school.
