Barrett Callaghan loved sports from the time he was a little boy. Whether he was playing football, baseball, basketball, or golf, he gave it his all. Beyond his talent as an athlete, Barrett was known for his big heart. His family and friends remember him most for his compassion, his loyalty, and the way he lived by the motto, “When in Need, I’m There.”
In September 2021, Barrett passed away at just 25 years old. His family donated his brain to the UNITE Brain Bank, where researchers diagnosed him with stage 1 CTE.
Barrett’s family and friends keep his memory alive through the Barrett “Bear” Callaghan WIN IT Foundation, hosting annual events in his honor, including Barrett’s WIN IT Invitational, a golf tournament that celebrates his love of the game. In just two years hosting the event, the foundation has raised over $35,000 for the Concussion & CTE Foundation to support CTE research, diagnosis, and care in Barrett’s honor. Barrett’s parents, Jan and Rich, also serve on our Chicago Advisory Board, helping further our mission to End CTE.
Through Barrett’s brain donation, his family’s advocacy, and the generosity of everyone who supported this year’s WIN IT Invitational, his legacy continues to do exactly that.
We’re incredibly grateful to the Callaghan family and to everyone who came together to honor Barrett while supporting our mission to End CTE. 💙
