The company was founded by Chairman, President, and CEO Bart O. Caraway, a CPA and licensed attorney with extensive experience in community banking and financial consulting at Briggs & Veselka Co. The executive leadership team includes Senior EVP and CFO R. John McWhorter, a 34-year banking veteran, and EVP and Chief Banking Officer Bill Bobbora, who previously held senior roles at Regions Securities and KeyBanc Capital Markets.
