The Work Horse

The Duffy Marketing logo is a visual representation of our philosophy when it comes to successful marketing. The horse on the logo represents your business and how successful marketing is built like a pyramid, with a strong foundation and multiple layers to support it. We take the longview and set each one of our clients up for success with a strong foundation, a smart campaign strategy, core advertising pieces and programs, and our expertise in managing your resources to produce successful results.

Like the draft horses of yesteryears Duffy Marketing is here to do the hard work for you. The hard work is building the elements of the foundation your business stands on. What do we mean by that? A foundation is not built on a single direct mail campaign. It’s not built on a single billboard. It’s not built by creating a Facebook or Twitter account and then ignoring it.

A foundation is built on a consistent effort over time to create a memorable public persona for your business. This means a campaign where all elements support each other. When people see your logo, they automatically know it represents your company. When they hear your musical jingle on the radio it reminds them it’s time to schedule their HVAC tune-up. When they see your company and employees present at multiple community events they know you truly are part of their lives.

Duffy Marketing specializes in marketing campaigns that are integrated and deliver the same message over and over again. A message inspired by market research that shows the best way to make your company stand out in the market. Each marketing element is like a finger on your hand. It can move independently but is most effective working with the other fingers to accomplish a common goal.

Take advantage of Duffy Marketing’s decades of experience to help your company reach its goal of dominating the market.
