Denny was born May 28, 1931 in Le Mars, the son of Robert and Clarissa Rees. He attended Carroll High School and Drake University where he was a four-year letterman for the Bulldogs in basketball, a sport which brought Denny and Grace together.
Following graduation and their marriage on June 1, 1952, Denny served in the Air Force at the rank of lieutenant, and after, began a successful career at Look Magazine in Des Moines.
When in his early 40s, Denny daringly started his own company, building it from four employees to more than 200. He was intensely concerned about his employees and their families, many of whom stayed life-long friends. During the flooding of 1993, while the Raccoon River was threatening his entire business, he was out running clean drinking water to his employees. The business survived that flood, but Denny soon after retired. The current owners still observe Denny's legacy having retained the Rees Associates name.
Denny enjoyed pheasant hunting with family and friends each fall, boating and vacationing with his family, and watching every game or match his sons and grandchildren participated in. Often alone and upper left in the stands, Denny was a quite cheerleader with a unique and resounding whistle, who inspired by always being there.
Denny loved animals, with a fond heart for a big brown dog.
Surviving are his children: Mark (Beth) of West Des Moines and Todd (Paula) of Amherst, Mass.; and grandchildren Jack, Joe, Logan and Taylor. He is also survived by his two sisters, Marian of Bainbridge Island, Wash., and Natalie of Cedar Rapids. Denny was preceded in death by his wife of 57 years, Grace Ellen; his parents Robert and Clarissa and his brother, Bobby.
The family will receive friends at 10 a.m. Friday, May 27, at McLaren's Resthaven Chapel, 801 19th St., West Des Moines, with a memorial service to be held at 11 a.m. A luncheon will immediately follow the service.
