Watched a clip of him years ago with my husband, talking about moving forward no matter what gets in the way. Never forgot it. 50 is no age at all.

Chris Kaag was a U.S. Marine Corps veteran, fitness entrepreneur and founder of the IM ABLE Foundation, the Berks County nonprofit that funds adaptive sports equipment and inclusive programs for people with disabilities. Born on 11 September 1976 at Cherry Point, North Carolina, he was medically retired from the Marines after an adrenomyeloneuropathy diagnosis at 21, then built Corps Fitness and IM ABLE around the mantra he learned at Parris Island: do not quit. He died peacefully in his sleep on Wednesday morning 30 September 2026 in Wyomissing, Pennsylvania, at the age of 50.
Kaag enlisted at 17 as a third-generation Marine. During boot camp at Parris Island his drill instructor Dave Hart's line "Don't quit on me, Kaag" became a lifelong refrain and later the title of his memoir. On a second tour at Aviano, Italy, in 1997 a duty-related concussion preceded the onset of adrenomyeloneuropathy (AMN), a rare genetic neurodegenerative condition. After weeks at Walter Reed Medical Center he was medically retired as a sergeant. He later said those months at Parris Island taught him to dig deep when the diagnosis threatened to define him.
He earned a business degree from Penn State, launched Corps Fitness from the back of a truck in 2004 in honour of his father Tom, and founded IM ABLE in 2007 to help people with disabilities live active lives. The foundation awarded hundreds of adaptive-equipment grants, backed inclusive projects such as a Womelsdorf splash pad completed in 2024 for a boy with a rare genetic disorder, donated a minivan to the Veterans Coalition of Pennsylvania in 2022, and promoted the slogan "No Excuses. Just Move." That same year Kaag was inducted into the Adaptive Sports Hall of Fame. He often said he loved giving people the chance to get out and live a fulfilling, motivating active lifestyle.
His memoir Don't Quit On Me appeared in 2026, with his wife Gretchen speaking to WFMZ about the book and their son Carter. Kaag remained a visible coach and speaker even when he relied on canes or a wheelchair. IM ABLE announced his death with condolences to Gretchen, Carter and the wider Kaag family, pledging to continue the mission he built. WFMZ and Berks outlets remembered a leader whose diagnosis never set the limits of his service to veterans, children and adaptive athletes across Pennsylvania.
