Jack’s 360-degree perspective derives not only from having run a one-truck company and a more than $500 million service company, but also from allowing hundreds of member companies to stand on his shoulders so they could see farther and reach higher. His unique point of view is shared throughout his book, “On the Shoulders of Giants.”

Currently, Jack and his wife of more than 30 years, Barbara, reside in Newport, Minnesota. They have two adult children, Lauren and Brent, and he is very proud of them. Jack is an avid outdoorsman who spends his free time flushing grouse behind his two springer spaniels or wading in a trout stream. He also curses at the TV on fall Sundays, thanks to a lifelong addiction to the Minnesota Vikings.
