David Lee Bos, age 81, of Hudsonville, passed away on Monday, June 29, 2020, due to Alzheimer's. Born in Holland to Henry and Myrtle Bos on September 6, 1938, Dave’s twinkling, mischievous brown eyes, his compassion and good cheer, and his Christian commitment will not be forgotten by his family and friends. He and his wife Nancy (VanRegenmorter) Bos, whom he loved beyond measure, would have been married 59 years on August 4, 2020. He also leaves behind his three children, Michael (Cheryl) Bos of Hudsonville, Jane Bos of Jenison, and Jackie (Doug) Roskamp of Holland; nine grandchildren: David, Christian, and Svetlana Bos,  Catherine “Catie”, Joseph, and Anna Luimes, and Abigail, Danielle, and Victoria “Tori” Roskamp. All of them loved him fiercely, and will miss his gentleness, his subtle, crackling humor, his warm and patient smile, and his upbeat, positive manner. He is also survived by his sister, Dawn (Jerry) Bredeweg of Holland; brother-in-law, Richard Brill of Grandville; as well as several nieces and nephews.  He was preceded in death by his parents; parents-in-law, Hubert and Catherine VanRegenmorter of Jamestown; sister, Mary Brill; and siblings-in-law, Roger and Martha VanKlompenberg. Dave graduated from Holland Christian in 1956, and earned his bachelor’s degree from Calvin College (1960) and master’s degree from Michigan State University. He spent 40 years at Unity Christian High School in Hudsonville (1961-2000), touching the lives of more than 7,000 students, and ended his professional career as the O-K Conference assistant commissioner (2000-2010). During his time at Unity, Dave taught physical education, physiology, and history for 32 years, coached boys’ basketball (26 years), baseball (15 years), and cross country (four years), and was the school’s athletic director for 17 years (1983-2000). While an athletic administrator, Dave guided Unity from a 3-year high school with 12 teams to a 4-year high school with 32 teams, including adding a dozen girls’ sports programs. He also was instrumental in beginning the Hudsonville Little League girls’ softball program in 1974, much to the delight of his daughters. His family plans to hold a private, faith-filled graveside service at a later date. Memorial contributions can be made in his name to Unity Christian High School, 5900 48th Ave., Hudsonville, MI 49426, https://www.unitychristian.org/.
