History
We started out as Sioux City District Telco Credit Union in 1945 to service those employees of the Sioux City, Iowa district of the Northwestern Bell Phone System and their family members. After the merger with the Health Triad Credit Union in 1983 a name-change was warranted and Telco Triad Credit Union was established. Continued growth has led to five locations throughout Sioux City, Spencer, and Denison, Iowa.
