County Line Construction

A company born out of passion and partnership

DJ Wassenaar founded County Line Farms in 2010 with a passion for agriculture, a love of equipment, and an entrepreneurial spirit. With the partnership of Matt Bergman (primarily an investor these days), Adam Tubman, and Dan Heeg—and an amazing and dedicated crew—County Line has grown and evolved into the custom excavation and construction company it is today. We are truly grateful for the communities we serve and our customers that support us. It's a gift to do what we love each and every day.
