In media, bigger isn’t always better.

MayoSeitz is fully independent. We call the shots, we don’t have to check in with corporate. In this business, reaction speed is everything. We’re flexible, nimble and quick – the envy of giant conglomerates.

Maneuverability drives innovation. We don’t need authorization to jump into new thinking, technology and techniques. Embracing change keeps us adaptable. At the leading edge.

It’s a case of nice guys finishing first. Our strategists are among the best in the industry. That’s what our clients say. And that’s one reason, of several reasons, why our average Agency of Record tenure is twice the industry average.

We’re easy to work with and hard to compete against, because our strategies get real results.

In our experience, that’s the best possible combination.

Our leadership team.

Our core values.

We’ve got your back. Today, tomorrow and in the future.

Do the right thing.

The best media planning is built on a foundation of professionalism, candor, and transparency. Business brings enough unknowns – your media partner shouldn’t be one of them.

Over collaborate.

Success is built on relationships and input is always welcomed, respected, and valued. Trust is our stock and trade and working together is the only way we know how to succeed.

Embrace change.

In media, one thing you can count on is that there’s rarely one thing you can count on. The landscape is in a constant state of flux. But with flux comes opportunity and we strive to always find the best route, even the uncharted ones.

Drive communication.

We believe in total transparency. It starts with a dialogue across every initiative. It continues with an open, flowing conversation to keep everyone on the same page, in the same mindset, and focused on the same goal: results.
