In 1979 Mark and Pat Kirschhoffer started a business at their family farm located at Russell Road and I-94 near the Wisconsin/Illinois border. Kirschhoffer Farms began with two trucks that hauled their own grain. When the trucks were idle, the decision was made to lease out the trucks to increase revenue. Thus became the beginning of Kirschhoffer Truck Service, Inc.

In 1984, the business became incorporated and is now widely known as KTSI. The company secured its own 48-state operating authorities and began hauling aggregates with dump trailers for several contractors in the area.  At the time, KTSI continued hauling their own grain as well as grain for various local farmers.


In 1999, KTSI moved from the family farm to the present location-ten acres off of HWY 41 with a staffed administrative office and a shop.

Since becoming incorporated KTSI’s fleet has grown to more than 20 company-owned semis as well as more than 10 owner-operator semis. While seldom hauling grain, the company has diversified the fleet to include not only dump hauling, but also flatbeds, lowboys, dry bulk tankers, and pneumatic storage pigs.
