Our History

During the first year, the company installed 27 phone lines, most of them connecting the businesses and suppliers of the company’s founders. During the next two decades, Paul Workman and his aunt grew the company to 443 phones before ultimately selling the company to E.L. and Mary Sanders Barnes on Mar. 10, 1912.
