In 2007 Bishop O’Hara and Bishop Hannan graduated their last classes, and the schools were closed. Holy Cross High School was then formed, which operated in the O’Hara building as the Dunmore Campus and in the Hannan building as the Scranton Campus. The Dunmore and Scranton Campuses retained the upperclassmen of the original schools, and all of the freshmen attended the Dunmore Campus. For the 2008-2009 school year onward, the Scranton Campus was closed, several modular classrooms were added on to the Dunmore Campus, and Holy Cross High School was physically united.
