Dr. William “Bill” Walter Iversen, 83, passed away peacefully at his home in Aurora, Colorado, on April 29, 2026, after a courageous battle with dementia. Born in Utica, New York, and raised in Clinton, Iowa, Bill will be remembered for his affectionate smile, his wonderful sense of humor, and his accomplishments both as an athlete and in his professional life.

By the time Bill was in eighth grade, he knew he wanted to become a dentist. He also pursued his passion for athletics, especially the game of golf, from a young age. Those who knew his family were not surprised by his abilities—his father was the Clinton City Golf Champion 25 times in 30 years. Bill proudly followed in his father’s footsteps, winning the Iowa Junior Amateur in 1959 and 1960, and leading the Clinton High School golf team to state titles in 1958, 1959, and 1960. Clinton High School recognized Bill for his accomplishments, inducting him into its High School Hall of Fame in 2016. These early interests became the foundation of his life and shaped everything he did.

Bill earned a Bachelor of Science in predental studies from the University of Wisconsin, where he lettered in golf from 1962 to 1964 and served as team captain during his final two years. He enlisted in the United States Navy in 1965 and served as a dental officer until 1971, including an assignment aboard the USS Klondike. During his service, he completed his Doctor of Dental Surgery degree at the University of Iowa in 1968. After fulfilling his Navy commitment, Bill returned to Iowa to earn his Master of Science in Orthodontics in 1973.

Bill practiced orthodontics in Ames, Iowa from 1973 to 1984, and later moved to Fort Collins, Colorado, where he continued his practice until retiring in 2009 and relocating to Anthem, Arizona to pursue more golf. During his orthodontics career, his patients recognized him for his professionalism and his charitable work helping underprivileged children achieve the confidence of a healthy smile. Always committed to supporting others in his profession, Bill even partnered with a colleague to develop a software solution for orthodontic practices—the Ortho Computer System—which revolutionized office management and is still used today by more than 3,000 practices in 10 countries.

Throughout his life, Bill devoted his time to service and community involvement, including Rotary International, the American Association of Orthodontists, the Fort Collins Chamber of Commerce, United Way, and the Rotary Breakfast Club, where he met his wife, Charlotte.

Golf was Bill’s true passion, and he played at the highest level for more than 70 years. During his remarkable golf career, he recorded 17 holes-in-one, was selected as a course rater for Golfweek magazine, competed in numerous Rotary International Golf Foundation tournaments, and served as an alternate for the U.S. Senior Open. As accomplished as he was, Bill was equally known for his patience and generosity with those new to the game, always willing to share his knowledge and encouragement. Many of the people he met on the course became lifelong friends.

Bill is survived by his beloved wife of 29 years, Charlotte; Tom Iversen, his brother and best friend, who shared his love of golf, hunting and skiing; his loving sisters, Lyn McAndrew and Jan Dugan; his five children, Rich Iversen, Laurie Baur, Teri Iversen, Carlie Odau, and Jason Odau; 12 grandchildren; and two great-grandchildren.

A funeral service with military honors will be held at Greenlawn Memorial Park in Neenah, Wisconsin.

Everyone is welcome to attend a celebration of Bill’s life on June 11 from 5:00 to 7:00 p.m. at the Fort Collins Country Club, a course that meant a great deal to him.

In lieu of flowers, the family suggests memorial contributions to The First Tee, in keeping with Bill’s love for golf and community service.
