From Getting Started to Going Big:

The O.C. Cluss Story

Founded in in 1918 in Uniontown, PA by Otto Charles (O.C.) Cluss, O.C. Cluss was incorporated a year later with O.C. elected president and general manager. After 40 years at the helm, O.C. turned the reins over to his sons, John and Charles, and brother-in-law, C.J. Barnes.

The new leadership of the 1960s established O.C. Cluss as a significant western Pennsylvania construction and building materials supplier. As Charles’ sons began entering the picture in the 1970s, company growth continued and O.C. Cluss evolved into the major regional lumber and building materials supplier it is today. The company remains privately owned and family operated.
