Dennis James Underwood

Born in Seattle, Washington, to Richard Underwood and Rosann Ness, Dennis grew up in Burien and graduated from Evergreen High School in 1975. It was during those early years that he met his high school sweetheart and the love of his life, Denise Lanouette. Married on June 9, 1979, they shared 52 wonderful years together, building a beautiful life and raising three sons, Christopher, Casey, and Ryan.

Dennis dedicated 40 years to The Boeing Company before retiring in 2016. He was an avid sports enthusiast, he had a special passion for softball and wrestling, spending more than 13 years coaching and mentoring young athletes. He took great pride in helping others grow, both on and off the field.

Dennis was known for his quick wit, playful teasing, unwavering honesty, and fierce loyalty to those he loved. He never hesitated to speak his mind, challenge someone to do better, or celebrate their accomplishments. He enjoyed golfing, boating, barbecuing, good wine, and, most of all, time spent with family and friends.

Together, Dennis and Denise built their dream home along the Columbia River in Chelan, Washington, where they shared countless memories with dear friends and family, including Jay, Danielle, Kayla. Kyle, Mike, Virginia, Terry, Margie, Kari, and Brian. Dennis also cherished the friendships he made at PebbleCreek in Arizona, especially the camaraderie and friendly competition of his recreational softball team. Whether gathered around the barbecue, enjoying the river, or spending time on the softball field, Dennis found his greatest happiness surrounded by the people he loved.

Dennis is survived by his beloved wife, Denise; sons Christopher, Casey, and Ryan; four grandchildren, Kayla, Aidan, Dylan, and Ashlyn; his dad, Norman; his sister, Darcy; and many extended family members and dear friends.

He was preceded in death by his mother, Rosann Ness; his birth father, Richard Underwood; his brother, Daniel Underwood; his sister, Karen Teachman; and his grandmothers, Lydia Underwood and Jeanne Baker.

Dennis lived life on his own terms, loved deeply, laughed often, and left a lasting impression on everyone fortunate enough to know him.

All of Dennis's softball family, friends and anyone else whose life he touched over the years is invited to join us in celebrating his life at a Memorial on Thursday, December 10, 2026 at 2:00 pm at the Softball "Field of Dreams", 15601 W Roanoke Avenue in Goodyear.
