McCall-Thomas Engineering was established in 1945 as a partnership by Arthur E. McCall and Henry C. Thomas and was incorporated in 1947. The company began operations in Charleston, SC and relocated to Orangeburg just prior to the third year of operation. We have two main operating divisions, the Electrical Engineering Division and the Communications Engineering Division, and we are an employee owned corporation.

The firm's first clients were electric cooperatives financed by the Rural Electrification Administration. By 1953, McCall-Thomas Engineering was providing services to eleven cooperatives within South Carolina. Several municipal electric systems were added by 1960, and the firm later expanded its practice to include electrical design services for commercial, industrial and governmental concerns. The Electrical Engineering Division continues today with a wide variety of projects and clients in the general area of power distribution and utilization.

The Communications Engineering Division was established in 1952 during the early days of the Rural Electrification Administration's telephone program. By 1960, engineering services were being provided to twenty-two cooperatives and independent telephone companies in three states. Since that time, the number and type of projects, as well as the variety and complexity of services available, have been greatly expanded. We take great pride in the fact that the firm has established continuing relationships and performed multiple projects with a majority of our clients. We are still providing services to the first client the firm ever had!
