William Mouw of the United States looks on during the pro-am prior to the Sony Open in Hawaii 2026 at Waialae Country Club on January 14.
William Mouw’s journey to PGA Tour victory is one that would sound unlikely on paper– yet the 25-year-old Californian has lived it, developing the grit and ingenuity that now define his golf career on a foundation built amid thousands of chickens.
Mouw talked about his upbringing on his family’s farm, and how those early days learning to work through problems shaped his mindset in golf.
Lessons in Hard Work and Problem Solving
Growing up on Billy’s Egg Farm in Chino, Calif., wasn’t just a childhood backdrop; it was a training ground. His father, who competed in college golf and briefly tested mini tours before planting roots, worked tirelessly before dawn to tend the chickens.
“We now have 30,000 chickens who wander freely within open-air buildings and lay about 20,000 eggs daily,” Mouw said. “Growing up, my three siblings and I would gather eggs and load them onto a conveyor belt into what’s basically an egg car wash. We’d shovel chicken poop and bag it for customers to use as fertilizer for their gardens, mow the grass and tend our drive-through window where about 300 cars come through daily to buy eggs.”
Mouw’s father didn’t just teach him how to work; he shaped his approach to adversity. “If a pipe breaks, you can’t just sit there watching water pour out,” Mouw reflected. “You’re always asking, ‘What can I do to make the most of this situation and move forward?’”–a mindset that translates almost perfectly to golf, where inevitable setbacks demand resilience and problem solving.
The farm itself doubled as an improvised golf range. The family’s five acres held space to hit balls just over the barns, where a 160-yard shot was maximum distance. Scraps of range balls found at local courses, like El Prado and Los Serranos, became practice fodder. What Mouw lacked in facilities, he made up for with hours of repetition and a self-made drive to improve.
Academically and athletically driven, Mouw excelled in multiple sports alongside siblings, but golf offered a singular test: your score never lies. “No matter how good or bad I was playing, I had to figure out a way to put up a score,” he said, emphasizing how competition drove his early development.
College Triumph and Pro Beginnings
Mouw’s amateur success eventually earned him a spot at Pepperdine University, a program steeped in competitive golf and known for refining young talent. In 2021, Mouw and his Waves teammates, part of one of the nation’s top Division I programs, clinched an NCAA Championship, a formative high-pressure experience before turning pro.
Graduating in 2023, Mouw entered the professional ranks via the PGA Tour University system, securing Korn Ferry Tour status based on his collegiate performance. Success there, including three runner-up finishes and enough points to finish 10th on the 2024 Korn Ferry standings, earned him full PGA Tour membership for the 2025 season.
Breakthrough on the PGA Tour
Mouw’s rookie season on the PGA Tour saw its share of ups and downs, with missed cuts and solid finishes alike. But his defining moment came at the ISCO Championship in July 2025. Entering the final round seven shots behind, the California native erupted with a final-round 61, birdieing half his holes and carding the lowest score of the day to secure his first PGA Tour win by a single stroke.
“It tells me that I have the potential to compete with the best talent on the tour,” Mouw said after the win, underscoring the confidence boost from closing out such a dramatic performance. That victory also secured his tour card through 2027 and moved him solidly into the FedExCup standings.
A New Chapter
While the ISCO Championship marked a professional watershed, Mouw’s personal life was changing too. In 2025, he and his wife, Hannah, welcomed their first child, a baby girl.
“Adalyn, who was born two months after that win. She’ll be out at some events next season, which I’m excited about,” Mouw said. “Becoming a dad changes a few things. For sure, it makes it easier to hit extra balls on the range. I’m not working hard for me now. I’m working hard for her.”
As Mouw competes at the Sony Open this week, the results underscore the reality of life on the PGA Tour. After opening with a 3-over-par in the first round, he sat tied for 101st, entering Friday still working to climb back into contention. It’s not the kind of start that grabs headlines, but it’s a familiar position for young pros navigating the grind of a full Tour schedule.
