He attended Grand Rapids Christian High School and graduated from Western Michigan University with his Bachelor of Arts Degree. He married his high school sweetheart and the love of his life Ellen (Petie) Steenstra on August 22, 1963.

John served in the Marine Corps from June of 1958 to April of 1962. He was honorably discharged due to injuries he suffered in a car accident which caused him great pain through his entire life. He continued work on his master's degree and began teaching at Grand Valley State College. In 1972, he earned his Ph.D. and moved to Greeley, CO where he began his teaching career at the University of Northern Colorado. He taught Sociology for 30 years and was a favorite professor and colleague to many.

John's faith in God directed his life and set the values for raising his family. He was active in his church through various ministries and Sunday School classes. He served as an Elder. He volunteered for many years at the Weld Food Bank and the Greeley Freight Station Museum. He served on the board of education at Valley School District RE-1 and spent many hours watching his children participate in their school activities. In the early 2000s, John spent three weeks in Pakistan advocating for the rights of young girls to be able to attend school.

John's hobbies included playing golf, riding his Harley Davidson, fishing, and working on model railroad projects with his son Joey. He enjoyed camping and going to Blues festivals in New Orleans and the Greeley Blues Jam. John loved to watch sports including football, basketball, baseball and golf, but he really loved hockey. He was a loyal Broncos, Rockies and Avalanche fan, but he especially loved the University of Michigan Wolverines (GO BLUE!).
