Glennon is a St. Louis based advertising agency with key experience in the automotive aftermarket, fast food, beverages, construction/development and consumer products.

For 35+ years Glennon has built a solid reputation for hard work, creative excellence, and strategically targeted campaigns. We believe in providing a select list of clients with a superior level of strategic thinking across all disciplines in developing ideas big enough to grow their business or brand.

Our philosophy is clear—we believe in being solution neutral, yet goal specific. We won't sell you on the idea of advertising just because we're an advertising agency. Better yet, we still believe in being an integrated marketing communications resource to the marrow of our bones. For our clients there is value in bringing everything they need from a marketing communications standpoint to the party.

Will it all fit? Will you need it all?

Maybe not all at the same time, but having the resources available sure does help us think about the big picture when we think about your business. It also allows us to uncover ways, often unconventional, to reach your target audience with your message.
