Dupaco Community Credit Union, based in Dubuque, and Bankers Trust Co., based in Des Moines, are named the top-rated credit union and bank in Iowa as part of Forbes’ first Best-in-State credit union and bank rankings. Forbes partner and research firm Statista surveyed more than 25,000 customers in the U.S. for opinions on customer satisfaction, trust, digital services and financial advice, among other categories. After disqualifying national financial institutions, just 2.4 percent of U.S. banks or credit unions were considered, Forbes reports.
