At SIGMA Marketing Group, our focus has always been a simple one: to turn customer knowledge into revenue opportunities, while expanding customer relationships and brand loyalty. It's a philosophy we've embraced from the very beginning. First as a marketing consulting firm, and today as a full-service database marketing company for a national client base of Fortune 100 companies. We've become an industry leader, not simply because of our expertise in a single area, but through the development of programs and strategies that continually integrate our collective strengths , and that complement the strengths of our clients.
