Nate Bunyak

Regional Director of Operations

Nate Bunyak brings a little bit of Pittsburgh grit and a whole lot of energy to everything he does. He is one of the Regional Director of Operations at CarolinasDentist focusing on our Triangle region, joining the team in 2026. Originally from Pittsburgh, PA, Nate graduated from Indiana University of Pennsylvania (IUP) with a degree in Marketing and Management—and has been putting both to work ever since. Three years ago, he traded in steel city winters for North Carolina sunshine—and hasn’t looked back.

When he’s not working, Nate is all about family life with his wife, Melissa, and their three kids—Bryce, Molly, and Connor. Whether cheering on their activities, exploring the outdoors, or simply embracing the joyful chaos of a busy household, he makes the most of every moment with his family.

An avid hiker and nature enthusiast, Nate loves adventures that combine fresh air, beautiful views, and lasting memories. That same adventurous, positive spirit carries into his work—he’s driven, all-in, and always ready to take on what’s next.
