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.

1994
Pro-Line expanded services beyond wood frame construction, and our first steel frame building was constructed for a client in Oskaloosa, Iowa.

2012
Pro-Line reaches the milestone of our 3000th structure built.

2023
The first Board of Directors is assembled to ensure the longevity of Pro-Line Building Company in serving generations to come.

Pro-Line constructed a new facility for our headquarters in New Sharon, Iowa.
