Dennis L. Arfmann

Mr. Dennis Leon Arfmann, age 74, of Boulder, CO, passed away Tuesday morning, October 21, 2025, at his residence. He was born February 12, 1951, in Neola, IA, a son of the late Leon and Vonda Arfmann.

Over his life, Dennis had many different passionate pursuits - tennis, the law, running, poetry, pickleball - but for him, the heart of living was the friendships he formed wherever he went. This is a skill he learned from his parents. In Neola, where he was born, he was the most popular player on the Volunteer Fire Department Little League Team. In Ralston, NE, where he attended high school, he formed life-long friendships with his classmates and neighbors - the 80th Street Crew. In Scottsbluff, NE, where he first practiced law, he was a founding member of the Platte River Yacht Club. And later in life, in Boulder, the Paisanos Book Club was a deep source of companionship, joy, and laughter.

Dennis was preceded in death by his younger brother, Rick Edward Arfmann.

He is survived by his wife, Julie Brown, his two children, Sara and Ben, his brother Bill, his nephew Josh, niece Adriana, and his cousins Bonnie, Heather, Mike, Doug, Marty, Greg, and Matt.

Dennis’ family will be holding a small, private gathering in early November. A larger remembrance ceremony is planned for Summer 2026, to be held in Boulder and featuring an ice cream truck - Dennis’ favorite indulgence. Details of this gathering will be shared at a future date.

Memorial contributions may be directed to the Tisch Brain Tumor Center or the Panhandle Humane Society, two organizations that Dennis loved and championed in his life.
