Just out of high school Ron Karr was hired by Knudson Mfg., the days most innovative designers of rollformers. After nearly 40 years in the rollforming industry, he became the most sought after service and sales technicians in the world.

Terri directs all financial operations of Karr's Building Supply & Service, but her knowledge extends far beyond the books. Her background in construction, rollformer sales and trade show marketing adds to the many services KBS can offer.

Roxanne is the spark plugs for the engine, nothing runs without her. From shipping to order processing to scheduling events she is the forefront of our operation and also has a vast knowledge of rollformers and their functions.
