Don attended Longmont and Niwot schools. He served in the U.S. Army during the Korean War.

Don married Glenna Trevarton on August 9, 1955. Their daughter, Ricque, was born in Longmont. The family then moved to the Western Slope, where daughter Nancy and son Jim were born. After moving to various Colorado cities, the family settled back in Longmont. Every summer the family took a vacation, visiting such places as California, the Grand Canyon and Yellowstone. Don and Glenna later divorced.
