Construction of our brand-new gym and fine arts center buildings began at the end of May 2018 and was completed for the start of the 2019–20 school year. The new fine arts center has significantly more wing space and backstage area, state-of-the-art computerized lighting, and sound systems, and nearly doubles the audience capacity of our old theater with seating for 750 people. Highlights for the new gym include an impressive two-story design with an indoor running track around the top level, as well as a substantial increase in seating capacity at 3,000.
