Built From The
Ground Up
Where It All Began
Richard and Sue Teunissen, along with their oldest son, Scott, established KSI Construction in 1992, followed by KSI Supply in 1997. KSI Construction was established in agriculture, becoming one of the first construction companies to pour a tapered bunker, which is how KSI got its start in silage bunkers.
After Richard bartered some work for a list containing a few names and a supplier contact, KSI Supply began to take shape with the idea of serving farmers from start to finish.
In 2014, the third generation joined the business. Michaela worked alongside Richard and Sue in the office, while Scott focused on growing the construction sided of the business. Following Richard's passing in January 2015 and Susan's retirement shortly after, Scott and Michaela continued building the family business.
Today, Scott's focus is primarily on KSI Construction, while Michaela's is on KSI Supply.
