Philadelphia Pennsylvania Regional Trucking Company. Greiner Inc was started in 1979 by Henry F. Greiner with one truck worked from his home. The company worked for construction companies moving jobsite and road materials. Henry did expand into the construction side of work gaining trucks, machines, and employees. Greiner Inc in the early 1990's sold off the equipment and kept just the trucks. Steadily the company has grown through the years. Brian K. Greiner started to take over the daily operations and is now CEO. We are regionally known for day leasing of dump trucks for construction industry projects. In the past few years under Brian's direction the company has opened up to large contract hauling of stone, sand, coal, gravel, salt, and mulch. Our capacity and regional strech now includes suppliers of Bulk Landscape materials to retail landscape outlets. With many years ahead and a large customer network we will be able to remain as one of the strong and consistent regional trucking companies.
