A proud graduate of the University of Wisconsin–Platteville, Justin holds a B.S. in Environmental Engineering with a minor in Environmental Science. His first paid job was with a landscape company, watering and fertilizing plants and even installing customer orders at their homes. If money were no object, he’d happily trade the desk for the driver’s seat as a heavy‑equipment operator—or embrace life as a self‑sufficient hobby farmer.

Outside of work, Justin enjoys time up north at his family cabin with his wife and their cat, golfing whenever he can, and volunteering at Marathon County Partnership for Progressive Agriculture events.

And here’s a fun fact you won’t find on his résumé: Justin spent five years playing sousaphone with the UW–Platteville Marching Pioneers—and still returns for alumni performances today.
