Executive Leadership

David L. Hannum, PE

Chairman-CEO

When he’s not contemplating the next goal of this $100.0M 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 a 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!

Ralph Wagle, PE

Chief Strategy Officer

Ralph is like Garmong’s Rubik’s Cube – remember those? Every twist of the game piece lines up a few more colors …or in our case, a few more pieces of our next project pursuit, our next client relationship, or our next opportunity for growth. Through his leadership, Garmong’s geographic footprint has expanded from Terre Haute to large offices in Indianapolis and Evansville; our projects now span the entire state. Annual revenues have grown from $20.0M to $100.0M, and employee count has tripled. When he’s not bound by the office, it’s quite possible he’s breathing in the beach air down south, or he’s discovered some hole-in-the-wall pub, and become fast friends with the folks at the table next to him – who were strangers just minutes ago. We can pretty much guarantee that before he leaves, his new friendship will have revealed some sort of connection back to Garmong…strategy.

Brian Kooistra, Leed AP

Chief Operating Officer

Whether he’s behind closed doors with the Executive Team weighing in on decisions that impact the future path of our company, providing guidance to a young project manager on how to have the tough discussion with a subcontractor when a long lead item doesn’t arrive as promised by the manufacturer, or dropping by a busy jobsite with a truck bed full of pizzas to celebrate a recent project milestone; Brian is dialed in on what it takes to make this massive construction machine operate.

Michael Preyss

Chief Financial Officer

Whether he’s makin’ it rain in the world of financials, or maneuvering through the rain in his Mooney, Michael’s crunching the financial numbers like he calculates his landing – meticulously. With additional duties over HR, IT, Contracts and all those other support services, Michael tries to navigate the terrain of people and money.

Paul Okeson

Vice President of Business Development

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?!

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

Regional Manager, Evansville

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 three 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.

Lance Gassert, PE, Leed AP BD+C

Regional Manager, Terre Haute

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 2-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.

Mitch Hannum, LEED GA

Regional Manager, Indianapolis

Mitch’s passion for construction began at a very early age. When Mitch was 5, 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.
