For this episode of the Data Center Frontier Show Podcast, DCF Editor in Chief Matt Vincent and Senior Editor David Chernicoff sat down for a far-reaching discussion with data center industry luminary Ron Vokoun, a 35-year veteran of the construction industry with a primary focus on digital infrastructure. 

"I got into telecom back in ’92, which led to data centers," he said. "Probably worked on my first one around ’96 or ’97, and I’ve been involved ever since."

Currently the Director of National Market Development for Everus Construction Group, Vokoun has been involved in AFCOM, both regionally and nationally, for nearly two decades and is an emeritus content advisory board member for Data Center World. He has also written extensively for Data Center Dynamics.

Vokoun added, "I’ve just always been curious—very much a learner. Being a construction guy, I often write about things I probably have no business writing about, which is always the challenge, but I’m just curious—a lifelong learner. Interestingly, [DCF founder] Rich Miller ... gave me my first blogging opportunity."
