St. Mary High School

In 1887 Richard Gilmour, then Bishop of Cleveland, had commissioned Rev. Dr. Thomas F. Mahar, pastor of St. Vincent Church,^[4] the oldest Catholic church in Akron,^[5] to establish a mission in south Akron. St. Mary Parish was founded by Rev. Mahar in 1896.^[6] The high school was founded a year later. St. Mary's athletic teams were formerly known as the Crusaders.^[7]

St. Vincent High School

A high school was opened in September 1906 to provide parishioners' sons with a classical education beyond grade school. The parish had already opened St. Vincent Grade School, Akron's oldest Catholic school still in operation.^[8] At the time of the merger, St. Vincent High School had graduated over 6,000 students.^[9]

In May 2013, St. Vincent–St. Mary alumnus LeBron James donated $1 million to the school for the purpose of renovating their basketball arena. The project included the installation of a new basketball floor, scoreboard, locker rooms, and bleachers, and the seating capacity, which was raised from 1,600 to 1,831. The subsequently renamed LeBron James Arena now also serves as home of the American Basketball Association's Akron Aviators.^[10]
