Denny's Excavating Inc was started in 1994 by Denny Leeuw. Denny started doing part-time work for farmers and residential customers on evenings and sometimes weekends while he still maintained his full-time job. In 1995, Denny resigned from his job and worked on his excavating business with his son Dan. The business expanded into new areas and flourished for several years as a family-owned business.
In 2004 Denny passed away, leaving Dan in charge of the business. Ryan Talsma joined his friend Dan in the business in 2005. Ever since they've been running the business as a team. To this day, they've retained the business as Denny's Excavating Inc in honor of Dan's father and company founder.
