Mariner High School was built in 1970. In the intervening 36 years, its doors have seen more than 10,000 graduates, plus an untold number of faculty and staff. The Mariner High School Alumni Association (MHSAA) is the dream of four members of Mariner’s first graduating class and one administrator: Their goal is “to reach, connect and celebrate alumni and friends of Mariner High School, to build lifelong relationships and to support Mariner High’s mission.”
