A relatively new bank to Sioux Falls is getting a new leader. Huron-based American Bank & Trust's long-time CEO Lynn Schneider is retiring at the end of the year. Doug Tribble, currently the bank's Sioux Falls market president, has been selected to replace him. Tribble, an Aberdeen native, has deep banking experience in South Dakota and elsewhere. He joined 125-year-old, family-owned American Bank & Trust two years ago, heading up the bank's expansion into the Sioux Falls market.
