The familiar yellow-and-blue colors, the quirky WaMoola and “Whoo-Hoo” posters — and other remnants of Washington Mutual’s brand — will disappear out of the local Washington Mutual branches by this June. New York-based JPMorgan Chase & Co., which bought the assets of WaMu last September, is in the process of rebranding the old WaMu branches and completing the transition to Chase.

Cindy Doty, Chase division executive for retail banking who overseas Western Washington, says the Chase logo will replace the WaMu one by June 1, but customers will be able to continue using their current account numbers, checks and debit cards, as well as have the same online, phone and ATM access. “It will be a smooth transition,” she said. “It will be easy for customers.”

The branches are also undergoing a physical change. Chase is removing WaMu’s signature “Occasio” teller stations, individual teller pods the bank introduced about nine years ago as a way of breaking “physical and psychological barriers” between customers and bankers.

“The teller stations will be replaced with the traditional teller line, which is more comfortable and easier to navigate,” said spokeswoman Darcy Donohoe-Wilmot.

Chase acquired most of the 119-year-old Seattle-based thrift for $1.9 billion after it was taken over by the Federal Deposit Insurance Corp. WaMu was the largest U.S. bank ever to fail.

Prior to this, Chase had no presence in the Northwest, and company officials said there are no plans to close any local branches. WaMu has nine branches and 10 ATMs on the Kitsap Peninsula. Chase previously announced layoffs of more than 3,000 WaMu in Seattle, all of them from WaMu headquarters.

Doty said although the look of the branches is changing, the employees are being retained, so “the same friendly faces” will greet customers. She said Chase has also committed to contribute $2.65 million in grants to nonprofits in its new communities this year, matching WaMu’s 2008 contribution.
