About 1st Security Bank of Washington

Headquartered in Mountlake Terrace, Washington, 1st Security Bank has been serving customers in King, Kitsap, Pierce, Lewis, Thurston, Grays Harbor, Snohomish, Clallam and Jefferson counties since 1936. With our twenty one neighborhood branches, we believe that bigger is not necessarily better. In fact, our strength comes from the relationships that we build with our customers, small businesses and community partners. Additionally, 1st Security operates lending programs for home buyers, local contractors, builders, mortgage companies and boat dealerships that help strengthen the communities in which we live and work. We aren't just open for business; we live here, which is why our branches are so involved with their communities. From sponsoring food drives to the annual Poulsbo Kids Day celebration, everyone at 1st Security lives our passion for being the bank that makes our customers say "wow"​. The Northwest is a diverse, open and welcoming community with many cultures and backgrounds that we celebrate, truly believing that we are stronger together. At 1st Security Bank our first priority is you, our customer, neighbor and friend.
