Heritage Bank began replacing signs on most of the Whidbey Island Bank branches last week, another step in the merger between two of Washington’s largest community banks.

Signs will be replaced at all four branches of Heritage in Whatcom County, and throughout Western Washington. The six offices of the bank on Whidbey Island will keep the Whidbey Island Bank name and signs.

The new logo aims to creates a consistent brand for Heritage, which has 66 branches mostly along the Interstate 5 corridor from Bellingham to Portland, Oregon.

Heritage and Whidbey Island Bank announced the merger in October 2013 and the merger was completed on May 1. Heritage’s headquarters are in Olympia.
