ABOUT

Senior-level marketing expertise without the full-time headcount.

Big Tuna Marketing partners with established companies and lean marketing teams to turn ideas into action — from strategy and campaigns to content, creative and execution.

Meet Liz

Hi, I'm Liz Mitchum. With 20+ years of strategic and hands-on experience building marketing departments from the ground up, I shifted my focus to work as a consultant to help companies make sense of today’s complicated marketing options to deliver results that matter.

With family at the forefront of every big career decision ever made, especially the launch of my own business, Big Tuna is aptly named for my two sons, whom we playfully call "Big Tuna" and "Little Tuna." (And yes, fans of The Office will appreciate the nod.)


Why Big Tuna?

 

Even established marketing departments don’t always have the in-house personnel, bandwidth, or specialized expertise to tackle every initiative. Other companies understand the value of marketing but don’t have dedicated marketing leadership or headcount in place. They know where they want to go—they need an experienced partner who can help turn ideas into action and keep things moving.
 

Whether you need strategic guidance, specialized expertise or simply an extra set of experienced hands, Big Tuna Marketing brings a fresh perspective and serves as a seamless extension of your organization or existing marketing team—without the additional overhead of a full-time hire or the learning curve of a less experienced resource.

With project- and retainer-based options, we can tailor our relationship to suit your company’s specific needs and goals.
