Comerica Incorporated is a financial services company headquartered in Dallas, Texas, strategically aligned into three major business segments: the Business Bank, the Retail Bank, and Wealth Management. Comerica, originally called Detroit Savings Fund Institute, opened its doors on August 17, 1849, to a city bustling with shipyards, river trade, sawmills, horse drawn carriages and dirt roads. Comerica ushered in a historic milestone in 2019 with the celebration of its 170th anniversary. Comerica’s longevity has earned it the distinction as Michigan’s longest serving bank.
