In the high-stakes world of the **LPGA Tour**, where precision, pressure, and mental fortitude define success, **Brooke Henderson** has always credited a key figure for helping her navigate the challenges and rack up an impressive 14 career victories, including two majors: her older sister, **Brittany Henderson**.
For nearly a decade, Brittany served as Brooke’s caddie, a role that went far beyond pulling clubs and reading greens. The partnership began in earnest around 2015–2016, when Brooke was just breaking through as a teenager on tour. Brittany, who had her own aspirations in professional golf, set them aside to support her younger sister full-time. What followed was one of the most enduring and successful sibling collaborations in the sport—13 of Brooke’s 14 LPGA wins came with Brittany on the bag, including the 2016 KPMG Women’s PGA Championship (her first major at age 18) and the 2022 Evian Championship.
Brooke has often opened up about how instrumental her sister was to her achievements. In interviews reflecting on their time together, she described Brittany as more than a looper—she was a best friend, confidante, and constant source of stability. “Britt and I have worked so well together for the past 10 seasons—and she is my best friend,” Brooke shared in one heartfelt discussion. “We travel together all the time… I could tell her anything and she kind of knew how to help me in any situation on or off the course. Just so much trust, you know, coming from that.”
That deep, unspoken understanding set their dynamic apart. On the course, Brittany’s presence allowed Brooke to focus purely on execution, knowing someone who knew her game—and her personality—inside out was handling the details. “We just know each other inside and out,” Brittany once explained. “My entire life she’s always been looking after me and making sure that I don’t do anything dumb,” Brooke added with a laugh, highlighting the protective, big-sister role that extended beyond yardages and club selection.
The bond was especially evident in high-pressure moments. Whether grinding through majors, representing Canada in three Olympics, or ending long win droughts—like her emotional victory at the CPKC Women’s Open—Brittany was there, offering calm reassurance and strategic insight. Brooke has emphasized how the lack of need for constant verbal communication was a superpower: they simply understood each other, reducing stress and allowing Brooke to play freely.
The partnership reached an emotional turning point in early 2026, when Brittany announced she was expecting her first child and would step away from full-time caddie duties after the season-opening Hilton Grand Vacations Tournament of Champions. Brooke described the change as bittersweet but exciting, thrilled to become “Aunt Brooke” while acknowledging the void left by losing her travel partner and trusted advisor. Veteran caddie John Killeen stepped in, but the transition underscored just how central Brittany had been.
Looking back, Brooke’s rise—from teenage phenom to one of Canada’s greatest golfers—owes much to that sisterly foundation. Brittany didn’t just carry the bag; she carried Brooke through the uncertainties of pro golf, providing unwavering belief, emotional support, and the kind of familial trust that no hired hand could replicate.
As Brooke continues competing at the highest level, the lessons from those years with her sister remain etched in her game: the value of deep relationships, quiet confidence, and having someone who believes in you unconditionally. Their story isn’t just about wins—it’s about the profound impact one person can have on another’s path to greatness. In Brooke Henderson’s words and career, Brittany’s role shines as a beautiful reminder that success on the LPGA Tour is often a family affair.
