John Grant "Ole" Olsen

June 20, 1933 - October 9, 2025

John Grant “Ole” Olsen died October 9, 2025. He was the third child to John and Nora (Abrahamson) Olsen. He was born June 20, 1933, in Philip, SD. He moved with this family to Sand Creek, WY, Spearfish, SD, Portland, OR during WWII, and back to the ranch near Hartley, SD. He learned a lot about hard work and resilience while living and working on the ranch. At Philip High School, Grant participated in every activity, was the class president, loved sports, and loved to sing. He graduated in 1951 and went on to attend the University of South Dakota where he earned a bachelor’s degree in Zoology. He made many lifelong friends at USD.

Following graduation, he served in the U.S. Army, spending most of his time in Okinawa, Japan, where he embraced new experiences—including mastering chopsticks, a skill he proudly passed on to his family. He insisted that his wife, children, grandchildren, and great grandchildren all learn how to use chopsticks. He completed his Army service at Fitzsimons Hospital in Denver and went on to sell flowers for Denver Wholesale Flowers for a couple of years.

In Denver, Grant met the love of his life. He married Nancy Elaine Howells on January 6, 1961. They moved to Rapid City where they made their life while he traveled and worked as a pharmaceutical sales representative for 29 years.

He was a fly fisherman, grandson of a homesteader, husband and dad, and a proud founding member of the Shrine of Democracy Chorus. Ole led an honorable life filled with adventure and fun, family, Christian faith, and generosity.
