While not in the office, Jeff can be found camping with his wife and two children in the Black Hills or fly-fishing in the mountains. His favorite travel destination is his family cabin in northwest Wyoming where he can relax and truly unplug. Jeff also appreciates a well-crafted cocktail or beer and enjoys cooking for friends and family.

Jeff once brought a giant fish-shaped pool floaty to Mexico. Against his better judgment, and his wife’s persistent requests, he earned the nickname “Dakota Jeff” from the other resort-goers by the end of the trip.
