James (Jim) Edward Grennan, Fort Collins, Colorado passed away August 14, 2024, after a long illness. He was born February 21, 1950, in Concordia, Kansas to John and Maxyne (Townsdin) Grennan.  Jim grew up in Jamestown, Kansas and graduated from Jamestown High School in 1968.  He later graduated from Cloud County Community College in Concordia, Kansas and then Kansas State University with a bachelor’s degree in Agricultural Education.  He lived in Colorado for most of his adult life.  He farmed and custom cut wheat from Texas to Montana and later owned a roofing company.

In 2021, Jim authored and published a book, ‘Raising Up Boys in Kansas’. He was always trying to help others.  He took numerous trips to St. Bonaventure Indian Mission in New Mexico with food and clothing.  He was an avid treasure hunter and always had his metal detector just in case.  He loved to play pool as well as chess.
