The basketball team visited a sports store in 1934 and was impressed by the large picture of a panther in the store’s display window, according to Mr. George Bender, class of 1937. The team, not having a mascot of their own yet, liked the idea of using the panther. By November 1934, the team was nicknamed the Panthers, a name which would eventually represent the entire school.CampusesThe current main campus, which houses grades 10-12 was built and opened in 1958.
