Our History

A man standing next to a red truck

A family operation builds a family of companies

Oak Management’s founders, the Rediehs family, has been immersed in the inner workings of the trucking industry ever since George Rediehs established his first carrier, Rediehs, in 1930. After taking some time to serve in the Army, he acquired Chief Freight Lines, adding a second carrier to the family business. The Rediehs family continued to operate both carriers for fifty years, building a special understanding of trucking, drivers, and all the logistics needed to ensure a smooth operation.

Multiple generations of next-generation service

The 1980s brought deregulation and an opportunity for greater autonomy for carriers. The Rediehs family seized on the opportunity in 1988, forming a company that would allow them to leverage their expertise in safety, compliance, accounting, payroll, logistics for the benefit of carriers: Oak Management. With Rediehs as their first carrier, they slowly began to expand, serving clients throughout the country and acquiring two more carriers, Combined Transport Systems and Steel Logistics, to bring the total of carriers in their family to four.
