David Copp Stringer, President
David is President and founder of Insignia Group, LC. A native of the Carolinas, he earned his Bachelors of Arts in English and minor in journalism from the University of North Carolina, Charlotte.
Not a typical “car guy,” David “fell” into the automotive business in 2000 by leading the development of Primesourceauto.com; the first fully-online automotive climate control catalog. This project led to the development of an online climate control catalog for Visteon, Inc. in 2001-02 and the development of ACDelcopartsonline.com, recipient of the “Web Catalog of the Year 2003” by the National Cataloging Managers Association.
Since 2002, Insignia has been a key contributor to the development of the GM Accessories network and is now an authorized provider of accessories catalog systems for Chrysler Motors, Kia Motors America, and Hyundai Motors of America. Stringer is a contributing writer to several publications and a frequent subject matter expert speaker at engagements such as SEMA and national conferences.
