North Dallas Bank & Trust Co. is making moves in its C-suite with four executive changes. The community bank announced four internal promotions for COO, chief lending officer, chief credit officer and chief human resources officer. The announcement of the new leaders comes less than a month after North Dallas Bank announced it had named a new CEO effective April 1. Here are the details of the changes: Brandi Shiflett, previously serving as senior operations officer, is the bank's new chief operating officer; Allen Hudson, formerly Dallas Banking Center president, is chief lending officer; James Tipton, former enterprise risk manager, is now chief credit officer; Pam Murray, former director of human relations, is chief human resources officer.
