About MDR Advertising
a Full-Service Advertising + Digital Marketing Agency

When something works, you keep it.

That’s why we’ve kept the same principles for the last four+ decades. And it’s why our clients hang around. MDR is founded upon partnerships that stick and ideas that work. So, while our office has grown and some faces have changed—our story hasn’t.

Tested & trusted by some of the strongest brands.

Founded on the simplest of principles. Do what's right.



“Most agencies go after the next big account. We prefer to build it.”

-Stephen Rybak, Principal
