About Lars Bergan

Thank you for your interest in Rotochopper equipment. Please feel free to contact me via the phone numbers or email address listed. I am excited to bring knowledge, enthusiasm, and creativity to whatever recycling project you have.

I have been working as a Rotochopper sales rep since 1999. Born in Chicago and raised in Madison, Wisconsin, I graduated from the University of Wisconsin with a BA in English, History, and Economics. Before coming to Rotochopper at age 27, I worked as a financial analyst in New York City, a researcher for the Library of Congress in Washington D.C., and a Fulbright Scholar in Kingston, Jamaica.

I live with my wife, Corina, and our two boys in southwestern Wisconsin. When I’m not working, I spend my time farming, coaching basketball, reading, or long distance running.
