About UsTelhio Credit Union has been a strong and stable financial institution in central Ohio since 1934. We are a not-for-profit, full-service financial institution cooperative, meaning our members are owners and can expect to receive high-quality financial services to meet all of their needs. Telhio is strong and safe, and has been serving Central Ohio for more than 75 years. Telhio began as a credit union for Columbus Telephone Company employees. The expanded vision of our board of directors and management staff took our credit union beyond just that select group. We now service all who live, work, worship and attend school in Franklin, Fairfield, Delaware, Union, Pickaway, Licking, Madison, Hamilton, Warren, Butler, and Preble counties. We also serve Select Employer Groups (SEGs) in a variety of industries including accounting, automotive, manufacturing, medical, real estate and telecommunications.
