The first building built specifically to house a high school in Wenatchee was the Whitman School, built in 1903 and named after Dr. And Mrs. Marcus Whitman, early missionaries to this part of the country. Although built as high school, students were shifted around to different schools and to rooms in businesses for several years.
In 1907 voters authorized purchase of a new site and a high school was built on Idaho and King Streets in 1909-1910. An addition to the high school was built in 1911. Classrooms were added and the auditorium enlarged in 1922. Special purpose rooms and classrooms were added in 1938, enlarging the building to 22 regular classrooms and 28 special purpose rooms. Portables were added adjacent to the high school as well, housing both high school and elementary classes.
