Created by Dow employees who chipped in to offer a $350 loan to a fellow employee, TDECU opened its doors in 1955. Beginning with volunteer workers we served our member-owners from a rented corner in the Franklin Insurance Agency Building. Over the past five decades we remain committed to the "People Helping People" philosophy in our expanding communities.
