The Sumner Group is a small to mid-sized advertising services firm based in Gastonia, North Carolina. Founded in 1987 by Michael D. Sumner, it began as Gaston County's only full-service advertising agency and has since broadened its capabilities to include advertising, marketing, design and public relations for clients across the United States. The firm emphasizes deep knowledge of a client's business and industry to identify differentiators and translate those insights into an integrated plan executed through multiple channels. Its client base spans diverse industries, and it positions itself as a partner for organizations seeking to cut through a crowded marketplace by aligning strategy with execution. In February 2025, Sumner Group introduced AI-powered solutions intended to deliver deeper market insights, streamline supply chains and reduce inefficiencies for its clients.
