Radio Nemo Interview with President Jon Coca

Independent Contractor
Here at Diamond mutual trust, respect, honesty and loyalty are the cornerstone that have kept my business successful and operating at a profit year after year. As a contractor Diamond is by far the best business partner in the industry! - Jamie
2019 TCA Driver of the Year (O/O)
We like the fact that Diamond is 100% O/O! As an O/O we operate as we wish to operate. We stay out as long as we want, and run as hard as we want. Diamond in return understands that. They find loads to accommodate and work for us. They realize that for their company to be successful we have to be successful! Diamond is a great company to work for!   --Kevin and Joy
