The Sells Agency is a full-service agency that provides marketing, advertising, and public relations. That’s us in a nutshell. But where did we come from? Well, we were founded in 1991 by Bob Sells as Sells and Associates. In 1995 his son, Mike Sells, joined the growing agency to handle the advertising side of the business. Thanks to his experience in the banking industry, financial clients signed on, and the agency continued to expand.
