In Memory Of
Donald J. Siekmeier
1925 - 2019

Husband and Father, Donald J. Siekmeier, died Wednesday, Dec. 4, 2019. He was 94 and full of years. Memorial service scheduled for 1 p.m., Thursday, December 12, 2019, at The Light of Christ Anglican Church, 4000 W. Yale Ave., Denver. His remains will be buried at Ft. Logan at a later date.

Don was born October 9, 1925, in Sioux Falls, South Dakota, to Leonard and Esther Siekmeier. He was the fourth of six children. He was predeceased by his parents and sister Janis Tiffany and brother Hugh. He is survived by his next older brother Leonard (of Colorado) and younger sisters Mary Child (of Texas) and Ruth Presto (of Connecticut). He was raised in Aberdeen, SD, and graduated from North High School in Omaha, Nebraska.

He married Gloria, his wife of 64 years, July 30, 1955. He and Gloria had four sons, Thomas (Claudette), John (Diana), Stuart (Jane) and Luke. He was beloved by his thirteen grandchildren and three great-grandchildren. He was affectionately known as “Uncle Donnie” by his nieces and nephews.

During WW II he enlisted in the U.S. Army Air Corps and served as an airfield fireman on Guam. He was discharged at Ft. Logan in 1946 and returned to the University of South Dakota, where he graduated with a business degree in 1950.

He began his career in sales for Aetna Casualty and then Technical Tape Corporation. In business with his brother Len at Colorado Pump and Supply (later CPS Distributors), he was a traveling salesman for 30 years in Colorado and other western states. He retired in 1985. At the time of his retirement, he had hundreds if not thousands of names written in countless small notebooks and had an equal number of stories about the people he’d met along the way.

He filled his retirement years with philanthropy, family support, golf, hunting, travel, bicycling, reading, and volunteering variously with the 1987 Denver Billy Graham Crusade, the annual Denver Post Ride the Rockies bicycle tour—where he was dubbed ‘Banana Don’—plus yearly bell ringing for the Salvation Army.

In 2010 he was invited on a Rocky Mountain Honor Flight for WW II Veterans to Washington, D.C, which sponsors veterans on a tour of the WW II Memorial, among other sites in our nation’s capital, as well as a banquet.

He was a faithful Christian and involved church member, beginning at St. Andrew Presbyterian and then at Bear Creek Presbyterian, later at Atonement Lutheran, and in recent years at The Light of Christ Anglican.

All the way to the end of his life, Don was happy and thankful. Don loved being with people and making them laugh. He made friends wherever he went. He relished family events, especially weddings. He was notably generous with his time, talent, and treasure.
