North Dallas Bank & Trust Co. appointed Larry Miller as new CEO on April 1. Michael Shipman, current chairman of the board and CEO, will retire March 31 and Miller, currently acting as president of the bank, will take the helm. Miller got his start at North Dallas Bank 38 years ago working in the mail office while he was still finishing his college degree. He said it was there that he began learning about the personality of the bank and making connections, and it wasn't until about two years later that he was fully entrenched in the credit side of the bank.
