TelComm Credit Union was originally chartered under the name of Springfield Telephone Employees Credit Union in June, 1940. Harry Duewel, a long-time Southwestern Bell employee was instrumental in organizing the credit union—as he quickly saw the inherent value in providing on-site financial services to his fellow telephone employees (and families). As a result, TelComm membership was offered by Southwestern Bell to its employees as a financial benefit—to exemplify the credit union philosophy of “people helping people”.

Today, TelComm serves over 23,600 credit union member-owners, including the employees of 125 companies (Select Employee Groups) located in Springfield and the surrounding area – in addition to the many members throughout the United States and abroad.
