Mr. Madson joined KATZEN in 1980 as a chemical engineer. Just three years later, his vision and dedication rewarded him the position of Vice President, in charge of marketing and technology. Pointing the way toward next generation technology, Mr. Madson became the new President and CEO of KATZEN in 1993, his current position. In his years at KATZEN, Mr. Madson has concentrated on value-added agricultural processing such as motor fuel, potable and industrial grades of ethanol. He has also been involved in vanillin, solvent extract, SO2 scrubbing, CO2 liquefaction, cane sugar processing, waste treatment systems, and cheese whey processing and conversion to ethanol. Mr. Madson has left no stones unturned in his lengthy and decorated career - from conceptual design to liaison during procurement, construction and production, he's been there. Mr. Madson routinely lectures and teaches leaders in the industry, serves as advisor to legal and financial firms and provides expert witness services. Mr. Madson prides himself in placing the right people in the right position and has done just that by personally interviewing and placing the majority of the current staff. He leads, directs, guides and advises in every aspect of KATZEN operations.

Before joining KATZEN, Mr. Madson worked for the Procter & Gamble Company for 9 years, becoming, at the time, the youngest employee to be promoted to the position of Associate Director, for Product Development. His work during those years included on-site liaison, definition of processes, cost/capacity improvement, process troubleshooting, and new product/process development in both cellulose and plastic systems. He left P & G to pursue his goal of developing, leading and partnering a touchstone engineering firm - thus KATZEN International.
