Leonard Cassens’ life could be summarized as a love to help and serve others. He started this service shortly after graduating from Bronson High School in 1944 when he enlisted and proudly served in the U.S. Army 78th Lightning Division during World War II and receiving an honorable discharge in 1946. He and his wife Juantia farmed between Climbing Hill and Anthon, where they conscientiously raised corn, hogs, soybeans, and most importantly, their son, Dr. Rodney Cassens. Leonard was on the Woodbury Central School Board, Farmers' Coop Board-Hornick for 30 years, serving nine years as president.
Leonard worked on the Woodbury County Fair Board from 1979 to 2006 and served as president from 1988-2001. During this time, there were many improvements to the fair. Some of the outstanding things that were added to the fair were Old Town and permanent sidewalks. He had a common-sense approach to managing people and problems. Leonard enjoyed visiting with people and watching the many families come back each year to enjoy the fair.
Leonard spent his life raising his family and farming in rural Woodbury County. He enjoyed fishing, hunting, camping, woodworking, spending time with his family, especially his two grandsons, and the Woodbury County Fair.
