Cliffside purchased Pioneer Supply in 2008.  Pioneer is a leading distributor of water and sewer pipe and other industrial products to contractors, city governments, and rural water districts throughout the state of Oklahoma.  The company was founded in 1965 and has a long history of providing a wide variety of industrial supplies with a solid reputation for service and quality.  Pioneer's ability to service over 700 accounts with a greater than 95% rate of repeat business is a testament to the management team's relationship with its customers, knowledge of its products, and ability to provide excellent post-sale service.  Cliffside is working closely with management to pursue strategic vertical and horizontal acquisitions throughout the midwest.



In 2007 Cliffside purchased Preferred Service, a North Carolina company that provides building maintenance, concrete polishing, and janitorial services to retail and industrial clients in the U.S.  Cliffside also purchased Preferred Floor Equipment, a company that leases, maintains and services equipment.  The combination of the two companies allows us to supply a broad solution of maintenance services and equipment to the most demanding national retail customers.  Preferred's reputation for professionalism, reliability, and developing innovative customer solutions has allowed it to aggressively grow market share.  Cliffside has worked closely with Preferred's strong management team to grow the customer base, pursue acquisitions, and develop new services for our existing customers.
