Senior Instructor

Gary Zimmer

Gary Zimmer was raised on a dairy farm in northeastern Wisconsin. He received training in dairy nutrition, earning a bachelors degree from the University of Wisconsin and a master’s degree from the University of Hawaii (1970). After achieving his educational goals, he spent the next five years teaching a farm operation and management course at Winona Area Technical Institute, Winona, Minnesota. In addition to nutrition, he was required to teach courses in crops, soils and farm finance. His approach to teaching included outside speakers, on-farm projects, field trips and much study. He has always asked questions and looked at many ways of farming with an open mind. This led him to discover The Albrecht Papers, Brookside consulting training, work as a private consultant in southeastern Minnesota, and ultimately to promote a better understanding and appreciation of biological farming.
