Our History

Roy Wolf was always a hard worker… At just 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 was 18 he went to live with them and began working in Wisconsin, and that’s where it all started. Take a trip down memory lane with us…
