Executive Leadership

David L. Hannum, PE

Chairman/CEO

When he’s not contemplating the next goal of this $200.0M company, you may find David enjoying an occasional exquisite cigar with good friends on his back porch, or cruising on his Harley through the backroads of the US and beyond. His 30+ years of leadership as its fourth-generation owner (plus growing up around the family business and the experience of learned lessons from the generations before him) has shaped Garmong into the successful company it is today. We add to this the talent of Garmong’s 150-deep employee family (up from 20 when David became owner). Our future is bright, we’re thankful for our successes, and we can’t wait to see what’s next!

Paul Okeson

President

Before many of us have left for work, Paul is already tuned into a client over an early morning breakfast meeting. Shortly thereafter, one might find him in the halls of the office reliving the last three seconds of yesterday’s NCAA game (where he likely entertained clients) with charades of final second three pointers as he heads to meet a client in conference room. Later that same day, it would not be unusual to find him running out of the office – cell attached to his ear – you guessed it, talking to a client – to mingle among central Indiana’s movers and shakers for an evening engagement. Paul is on 24/7. In addition to being well connected, he is also well-versed as a public servant through his time as former Indianapolis Mayor Greg Ballard’s Chief of Staff, and did we mention he played an instrumental role on the Indianapolis Super Bowl Committee?!

Lance Gassert, PE

Chief Operating Officer

Lance is precise and strategic – in thought and in action. He’s also witty and, we’re pretty certain, a comedian in a former life. But first, back to the serious side. To his professional world, Lance brings an uncanny ability to see two-dimensional systems spatially and communicate ideas and interpretations into clear and concise directions. When it comes to his work away from work, rebuilding his grandfather’s 1966 International tractor isn’t a greasy playground as one might imagine, but more of a strategic puzzle of shining engine components with rubber gloves required, calipers for accuracy and then, and only then, calculated placement. And, when he has a microphone in his hand – company function or not – you’re guaranteed one of those good laughs. You know, the kind where your stomach hurts from laughing the next day. Total mic drop.

Dan Zuerner

Vice President of Business Development

While Dan’s primary responsibility is to fill Garmong’s project pipeline, he is anything but your typical salesman. As a competitive sporting clays shooter for decades, Dan’s ability to maintain mental focus under pressure has been tested over millions of shotgun shells. Likewise, his established reputation of providing clients with frank perspectives and solid advice to culminate successful project outcomes involves just as much targeted attention. In Dan’s world, more often than not, such discussions will involve some component related to economic development.

Jeremy Kunz

Vice President of Strategic Initiatives

Jeremy’s always been a runner – not like Run Forrest Run, more as in a five-time collegiate All-American in Cross Country and Track and Field from back in his college days. Today, all those years of training and self-discipline are coming in handy personally, as he and his wife raise four young children, often sharing stories (not for the faint of heart) that provoke out loud laughter; and professionally as he chases future projects and employee talent for Garmong’s Evansville office.

Mitch Hannum

Vice President of Business Development

Mitch’s passion for construction began at a very early age. When Mitch was five, his family broke ground on a new home on their property in Terre Haute. Each day, Mitch would greet the crew on their way in and attentively watch their progress from as close as his mother would allow. When quitting time came for the men hard at work, Mitch would race onto the site, run up the hills of dirt, climb over the equipment, and put on his best impression of the activity just performed. The passion for construction that Mitch developed in those early days has gotten a lot more serious since he started working full-time in 2010, but his fascination with construction is what continues to drive him.
