Previously, the Washington and Idaho branches had operated under separate brands such as First Savings Bank, Whatcom State Bank, Seaport Citizens Bank and Towne Bank.
In 2010, Mark J. Grescovich was named president of Banner Corporation and Banner Bank. A few months later, Banner Corp sold 75 million of its shares to raise capital.
