John grew up in north central Oregon and was actively involved in 4-H for 10 years. He worked for family and area winter white wheat and cow/calf ranches until completing his bachelor degree at Oregon State University. He then earned his Master’s degree at Oregon State University specializing in reproductive physiology.
John began working at K-State Research and Extension's Agricultural Research Center in Hays in 1986 as the cow/calf herdsman and assistant scientist. He returned to Oregon in 1994 and worked as the ranch manager – assistant scientist at the Eastern Oregon Agricultural Research Center – Union Station for Oregon State University until 2000. He completed his PhD. in reproductive physiology, focusing on bull fertility, from Oregon State University in 2004.
John began work at K-State Research and Extension's Agricultural Research Center in Hays in 2005 as the Beef Cattle Scientist. He is particularly interested in cow-calf production systems that will reduce production costs and result in value-added beef carcasses. Early weaning of calves may be a low-cost sustainable system that will reduce cow maintenance costs, increase the pounds of beef raised per grazed acre, as well as improving cow performance and carcass quality of offspring.
John along with his wife, Elizabeth, and their children Cora, Amelia, Tygh and Levi enjoy their 4-H cattle, family deer hunting, and riding their mustang Reno. Cora is currently pursuing a Master’s degree in English at KSU following the completion of her Bachelor’s degree in Elementary Education. John and Elizabeth enjoy watching their three younger children complete in swimming and traveling to swim meets.
