Originally built in 1935, with a campus on the east side of Lake Forest, the high school expanded to a second campus on the west side of town within the last three years. The east campus continues to act as the academic center, while the west campus is home to district offices and athletic facilities, including a football stadium, baseball and softball fields, soccer fields and tennis courts.
