Our History

Roy Wolf was always a hard worker… Before he was even 14 years old he was truck driving in Iowa. We assume this must have been legal back then! Roy had family in Theresa, Wisconsin. When he turned 14 he went to live with them and began working on the family farm in Wisconsin until he was 17, and that’s where it all started. Take a trip down memory lane with us…
