Beloved husband, father, grandfather, uncle, brother, and dear friend, David Ladd passed away on January 17th, 2026, at the age of 89. David was born and raised in St. Louis, Missouri and lived his retirement years in Boulder and Steamboat Springs Colorado. His love for all things outdoors and his love of engineering was only surpassed by the love he had for his family. The seventy year relationship he had with his wife and soulmate Alice, was like no other. They shared an unbreakable bond. The times Dave and Alice spent hiking and enjoying the serene beauty of the mountains brought out the happy free spirit that defined him. Dave is survived by son Matt, daughter Kathy, daughter in-law Kris, and grandchildren Tyler, Kara, Katy, and Thomas, and brother Bill. A memorial service will be held at Crist Mortuary in Boulder, Colorado (3395 Penrose Place) on Monday, January 26th at 10:30 MST.
