Who Is Brooke Henderson's Caddie?
Since turning professional, the Canadian has had her older sister, Brittany, on the bag
www.golfmonthly.comBrooke Henderson is starting 2026 with a new caddie setup, as her long-time sister Brittany Henderson steps away due to Brittany’s pregnancy. For most of the season, Brooke has rolled with veteran caddie John Killeen on the bag, beginning after the season opener in Orlando. A final appearance with Brittany occurred at the Hilton Grand Vacations Tournament of Champions, with Brittany then focusing on family, and Killeen stepping in for the remainder of the year.[1][2][3][4]
Key details
- Brittany Henderson served as Brooke’s caddie since 2016, but paused on full-time duties in 2026 because she and her husband are expecting their first child in June.[2][1]
- Brooke opened the 2026 season with Brittany for one event before transitioning to John Killeen for the rest of the year.[3][1]
- The change was publicly discussed in January 2026, with subsequent coverage confirming Killeen’s role and Brittany’s eventual temporary departure from the bag.[4][7]
What this means for Brooke
- Expect a shift to a more veteran, steadier pairing on the bag as she adjusts to life without her sister-caddie, at least for part of the season. The new arrangement aims to maintain continuity as she competes across a demanding LPGA schedule, including Asia Swing events later in the year.[7]
- The dynamic of a longer-running family partnership changing can impact on-course communication and feel, but many players have successfully transitioned to seasoned looper teammates mid-career.[9][3]
Illustrative note
- Brooke’s 2025 CPKC Women’s Open win underscores how quickly on-course partnerships can influence performance; the 2026 changes come as she builds around a new caddie lineup while Brittany focuses on family.[1]
