The Colorado community is mourning the loss of Dustin Duff, who passed away surrounded by love on Friday, August 21, 2026, at Pathways Care Center in Fort Collins. His death has left family, friends, former colleagues, fellow coaches, and the many young athletes he mentored grieving the loss of a devoted husband, public servant, coach, and friend.

Early Life and Family

Dustin was born on April 26, 1984, to Steven Duff and Yvonne Younger. He grew up in Thornton, Colorado, where he formed friendships and created memories that remained important throughout his life.

As a young man, Dustin enjoyed exploring his hometown and playing sports with his best friend, Jason. He graduated from Thornton High School in 2002, and during those years he met Jenna, who would become his wife and lifelong partner.

Dustin later attended Metropolitan State University, graduating in 2006 with a degree in criminology. On July 7, 2007, he and Jenna were married. Their relationship was built on love, loyalty, friendship, and devotion, and they remained committed to one another throughout their marriage.

A Life of Service

Dustin’s professional career reflected his strong desire to serve others. He began his working life as a wildland firefighter stationed in Red Feather Lakes, Colorado.

He later entered law enforcement and became a Denver police officer. During approximately a decade with the Denver Police Department, Dustin dedicated himself to helping others while developing lasting friendships with the people he worked alongside.

After retiring from police work, Dustin became a Realtor, a career that provided greater flexibility for him to pursue one of his greatest passions—football.

A Passion for Football and Coaching

Dustin was a devoted CU Buffaloes fan and had loved football from an early age. He played in youth leagues and continued playing through college until an injury ended his playing career.

Rather than leaving the game behind, Dustin found another way to remain involved. He began coaching, eventually working with high school football programs at several schools throughout Northern Colorado.

For Dustin, coaching was about far more than winning games. He invested his time, knowledge, energy, and heart into his players and wanted them to succeed both on the field and in life.

Over the years, countless young athletes were influenced by Dustin’s encouragement and belief in them. He considered his players and fellow coaches an extended family and affectionately referred to them as “his boys.”

To many athletes, Dustin was more than a coach. He was a mentor, supporter, trusted role model, and someone they could depend on.

Outside of work and coaching, Dustin loved spending time outdoors. He was an enthusiastic fisherman and hunter and treasured the adventures he shared with family and friends.

Those experiences created countless stories and memories that his loved ones will continue to carry with them.

A Runner Who Never Gave Up

Later in life, Dustin discovered a passion for running. What began as a simple challenge to run to the stop sign down the street eventually developed into a much greater pursuit.

He embraced the discipline and challenge of the sport and completed his first marathon in 2020.

Dustin continued pushing himself, eventually taking on the remarkable challenge of completing a 50-mile race. His accomplishments reflected the determination and perseverance that characterized so much of his life.
