Gregory Welteroth Advertising (GWA)

Gregory Welteroth Advertising (GWA) is a privately-held advertising and marketing company that specializes in media buying strategy, cooperative retailer-based programs and national branding campaigns. Located in central Pennsylvania, we have spent the past 30+ years working with national and international brands to create programs that increase sales and brand awareness. We are not your typical agency, and we have no intention of being one. We’re not in business to win awards; we’re in it to save you money, sell products, overcome competitors and make a noticeable difference in your bottom line. 

We have been successful in utilizing efficient media buying and marketing strategies to deliver positive sales results to over 4,000 independent retailers, as well as national and international brands. Our relationship with these companies allows us access to practically every market in America, and our strong relationship with the media allows us proprietary pricing models for our clients. 

GWA's team of companies is full-service, offering creative services,market analysis, media negotiation/buying, verification, internet marketing, website design, and more. We believe our programs work because we have the experience and resolve to make them work, time after time.
