Bank of Hawaii Chairman, President and CEO Peter Ho said: “Wayne’s depth of experience and strong ties to the community have made countless contributions to the success of our business clients over the years. He will always be a part of our Bank of Hawaiʻi ‘ohana, and we are deeply grateful for his leadership and commitment to building partnerships across the state.”

In advance of Hamano’s retirement, Bank of Hawaiʻi announces the following appointments and promotions:
