About Pro-Line

Serving Iowa Since 1986


Pro-Line began to serve rural Iowans—our neighbors—and has expanded to serve Iowa’s growing communities through our commercial and municipal services. No matter how much we grow, our values remain the same: providing you with a quality construction and a quality partnership.

1986

Pro-Line Building Company was founded by Kenny Van Kooten in 1986.

Pro-Line expanded services beyond wood frame construction, and our first steel frame building was constructed for a client in Oskaloosa, Iowa.

2023

The first Board of Directors is assembled to ensure the longevity of Pro-Line Building Company in serving generations to come.
