Additionally in 1934, Western Academy reorganized and was then renamed to Western Christian High School. By 1940, Western Christian High School had over 100 students, serving grades 9-12. The new school that had been started years prior was completed in 1948, However, as enrollment continued to rapidly increase, the building also grew to accommodate the students. Throughout the 1950s-1970s, additions were added to the then-completed building: a gymnasium in 1957, a modern music facility for band and choir in 1964, a science wing in 1968, a wood shop and home economics room in the mid-1970s, and a second gymnasium in 1978.
For almost fifteen years, the building was able to sustain its growth. In 1994, a new construction project began, remodeling the three main floors of the original building. In 2008, the athletics department saw a need for a weightlifting room and our busing department saw the need for a bus barn. As these were added, another major renovation was underway. In 2015-2016, the school received another update to the science wing, music facility, and original gym (built in 1957) that was converted to an event space. During this time, upgrades were also implemented in the entrance and lobby.
