During his growing up years, Greg was active in football, basketball and track. He was also active in Boy Scouts achieving his Eagle Scout during his senior year. Greg graduated from Windom High School in 1967. He earned his bachelor’s degree at Morningside College in Sioux City, Iowa, before earning his doctorate in dentistry at the University of MN, Minneapolis in 1975.
Upon graduation Greg joined his father’s dental practice in Windom. Greg later took over the family business and remained there for 42 years. He was known by many of his patients as the “gentle dentist.”
For more than 25 years, Greg sang in the church choir. He was also active in the Noon Kiwanis group.
In 1990, Greg met Cathy Hopkins in church choir, and they were married on July 5, 1991, at the First United Methodist Church in Windom.
His loves were fishing, duck hunting with his family and friends, canoeing/kayaking, biking, bird watching and spending time on any lake. Annual trips to the Boundary Waters were always a highlight of Greg’s life, whether solo or with friends.
