The experience that these individuals bring rounds out our team and clearly positions us to propel the bank to its next level.”

“Commercial lending is at the heart of what we do, and Mr. Hansen brings the expertise needed to drive sales, reduce risk, and grow relationships,” said Daugherty. Hansen has proven success in his career in generating new loans and

commitments, obtaining new relationships, reducing risk rated assets, and increasing market share. Mr. Hansen replaces former EVP of Commercial Lending Duane Brandenburg, who has left the bank.

“I feel completely confident that we have assembled an extremely qualified group of executives whose combined energy and experience will take this organization to the next level,” said Daugherty, who joined AmericanWest Bancorporation as CEO in September of 2004. “We now have the skills, the commitment, and the direction to grow this company, while keeping our eyes firmly focused on the fundamentals of community banking.”
