In October of 1999, Pinnacle Distribution Concepts (PDC) joined DuPont Surfaces as an authorized distributor of DuPont Corian® solid surfaces and as an authorized marketer of DuPont Zodiaq® quartz surfaces. On February 2, 2010, the owner retired and PDC closed. The new DuPont distributor for this geographical location is Hallmark Building Supplies.
