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.


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.


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


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

Jim VanderBeek began his career at Pro-Line in 1989 working under Kenny Van Kooten. Jim and his wife, Barb, purchased Pro-Line and immediately began to grow the company three years later in 1992.


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


Bill Maschmeier becomes owner of Pro-Line, providing the next generation of leadership and vision for the future.
