Phillip Joseph Keuhlen, Age 75, passed away at home in Richland, Washington, on June 21, 2025.

Born in Montclair, New Jersey (though we won’t hold that against him), Phil lived a life of purpose, service and curiosity. He entered the United States Naval Academy in Annapolis Maryland, graduating with the Class of 1971. His distinguished Navy career included Command of U.S. Navy fast attack submarines – An honor earned through dedication, intellect, and steady leadership.

After retiring from active duty, Phil briefly pursued studies in architecture at the University of Washington before returning to the nuclear industry. He contributed significantly to national efforts at both the Savanah River Site and Hanford Site, managing programs that advanced the safe handling and disposal of nuclear waste – work he approached with his characteristic focus and integrity.

A lifelong marksman, Phil was a New Jersey state champion in target shooting in his youth. In retirement, he rediscovered that passion and became an enthusiastic member of the Tri Cities Shooting Association, competing in smallbore rifle matches and mentoring others with a not-so quiet confidence. In 2023, Phil placed 5th in the Eley Benchrest Masters Final, a worldwide competition.

Phil is survived by his wife Susan; his sons, Michael and Kyle and his wife Claire; his daughter, Heather and her husband Matt; and his granddaughter, Elizabeth. He is also survived by his siblings – Chris, Danny, Joe, Larry, Rosie, and Suzie. Also of note, were his beloved Bouvier des Flandres dogs, Koa and Keiki, who were cherished companions and avid moochers of chicken nuggets, dutifully supplied by Phil.

In recent years, Phil became active in advocacy through organizations like the Calvert Task Group. He contributed articles and co-authored parts of the group’s book, Don’t Give Up The Ship, passionately defending the importance of keeping political agendas separate from naval readiness. His focus remained on strengthening the Navy as a unified, mission-ready force – values he lived throughout his own service.

Phil’s memorial service will be held on Saturday, July 26th. from 10AM to 1 PM at Einan’s at Sunset Gardens Funeral Home, 915 Bypass Highway, Richland, WA. A reception will follow the service.

Phil was fond of saying, “Perfection can be improved upon.” It may sound puckish, but those who knew him best know he meant it. We will remember him for his unwavering standards, sharp wit, steady presence, and deep love for his family and country – and we will strive, as he did, to always improve upon even the best.
