John Robert Sack

John Robert Sack, 65, passed away peacefully on November 6, 2025. He was born on May 23, 1960 in Denver, CO to parents John and Viola. John is survived by his loving wife, Warine, and their children, John Joseph and Ryan.
John dedicated 29 years as an airline mechanic inspecting, repairing and ensuring safe flights with Continental and then United Airlines. During this time he met the love of his life, Warine through mutual friends, and married on April 15, 1995. The pair welcomed their first son, John Joseph in June 1996 and second son, Ryan in October 1999.
After a long and fulfilling career, John retired in 2020. He and Warine would enjoy annual trips to Key West, visiting their sons in Hawaii and San Diego, and the peace and quiet of their home in Denver, CO. Like many in his family, John had quite the green thumb and spent his days farming wheat and tending to his home garden. Whether it was through the vegetables he grew or the nights he spent working, John always provided for his family.
John always had a strong sense of self and never shied away from doing what was right for his family. He lived every day to the fullest and his presence will be greatly missed. To send flowers to the family or plant a tree in memory of John, please visit our floral store.
