Robert Jeffries was hired as manager in 1960. In the winter of 1960 and early 1961, 485 subscribers were added to service with the acquisition of four more exchanges: Hardesty, Eva, Griggs, and Felt-Wheeless. The Logan exchange in southern Beaver County followed in April of 1962, and in January of 1963, the Kenton exchange was added.

Continued growth and expansion of facilities made it necessary in 1962 to raise money for the new installation and the construction of a headquarters building. This building was located at 603 S. Main Street, Guymon, Oklahoma, and continues to serve as the cooperative's headquarters to this date.

In 1967, the cooperative secured a loan from REA in the amount of $1,640,000 to upgrade service from an eight-party system to a four-party system, extending and replacing old lines with buried cable.
