Initially located in the educational complex on Park St., formerly occupied by Walla Walla High School, WWCC later relocated to its current site east of town near the airport, after outgrowing its original location.

Additionally, a branch campus was established in Clarkston, WA, 100 miles to the east.

In the late 1990s, WWCC introduced one of its most significant programs, the enological and viticulture program, amid economic uncertainty in Walla Walla caused by the local decline in the agriculture industry.
