Welcome To A Higher Standard of Value

Two great companies are merging to provide the best customer experience in the commercial truck and bus industry. As a combined company, Roberts Truck Center and Diamond Companies will serve 26 markets in 7 states with 1,300 of the best employees in the industry. We will have the scale and resources to provide even better transportation solutions and services to move your business forward.
The merger will be effective January 1, 2014. Until the transaction closes, each company will continue to operate separately. Nothing about our relationship or the way you do business with us will change.
We will remain a privately held company, and we will continue to bring a higher standard of value to the market place through our integrity, quality and service.
