Early Life and Belgian Roots
Born in Villers-la-Ville, Belgium, Adrien Dumont de Chassart’s journey into golf began on European soil. From a young age, he demonstrated a natural ability for the sport, quickly rising through the amateur ranks in Belgium.

Adrien Dumont de Chassart: Career
Collegiate Career at the University of Illinois
To further sharpen his game and gain exposure to U.S. college golf, Dumont de Chassart enrolled at the University of Illinois — a powerhouse in NCAA golf.2
There, he became a crucial member of the Fighting Illini golf team and developed under the guidance of esteemed coach Mike Small. His collegiate tenure was marked by multiple accolades, including All-American honors and team successes.
One of the highlights of his amateur career came in the Arnold Palmer Cup, where he represented the International Team in 2021 and 2022.
Despite the team’s loss to the USA in 2021 (33-27), they bounced back the next year, defeating the Americans by the same score. These experiences honed his match-play skills and gave him valuable exposure to elite competition.
First Taste of a Major: 2022 U.S. Open
- Dumont de Chassart earned a coveted spot in the 2022 U.S. Open at The Country Club in Brookline, Massachusetts.
- He qualified by shooting a 4-under-par 136 at the Springfield Country Club final qualifier — an impressive feat for a first-timer. Though he missed the cut after two rounds with a 7-over score, the experience was invaluable.
- For many young players, just making it to a major championship is a dream. For Dumont de Chassart, it was a stepping stone that further ignited his professional ambitions.
- After graduating from Illinois in 2023, Dumont de Chassart made his professional debut on the Korn Ferry Tour — and it couldn’t have started better.
- In June 2023, he won his very first professional tournament: the BMW Charity Pro-Am. He defeated veteran Josh Teater in a one-hole playoff, announcing his arrival in emphatic fashion.
- He almost repeated the feat just weeks later at the Blue Cross and Blue Shield of Kansas Wichita Open, finishing tied for second after losing a three-man playoff to Ricky Castillo.
- Such performances were enough to earn him the Korn Ferry Tour Rookie of the Year title for 2023 — a clear signal that he belonged at the highest level.
Transitioning to the PGA Tour
Thanks to his performance on the Korn Ferry Tour, Dumont de Chassart earned a PGA Tour card for the 2024 season. He featured in 27 events that year, making the cut in 12 of them — a respectable stat line for a rookie adjusting to tougher competition and more demanding courses.
His two standout performances on the PGA Tour came at:
-
2024 Puerto Rico Open – Finished T6
-
2024 Butterfield Bermuda Championship – Shared T3 with Mark Hubbard
Both events showcased his ability to compete under pressure and stay in contention through four rounds. With each outing, he gained critical experience and confidence.
2025: A Year in Progress
In the 2025 season, Dumont de Chassart has played in three PGA Tour events so far. While he missed the cut in two of them, he managed to finish T26 at the Puerto Rico Open — a solid result and a sign that he’s steadily refining his game.
The start to this season suggests that he is still in the process of finding consistency but possesses the tools to climb the leaderboard in upcoming events.
Even while making his mark in America, Dumont de Chassart hasn’t forgotten his European roots. He has been a part of the DP World Tour (formerly European Tour) since 2016, though without a title to his name as yet.
However, his recent T8 finish at the 2025 Qatar Masters was his best showing to date on the European circuit.
This dual-continent schedule speaks volumes about his ambition and adaptability. Competing on both sides of the Atlantic offers Dumont de Chassart broader opportunities — not just for wins but for World Golf Ranking points and Ryder Cup consideration.

With impressive performances on both the amateur and professional circuits, his calm demeanor and consistent play have earned him a growing fanbase.
However, for many fans, interest in Adrien extends beyond the golf course. A common question that pops up about the athlete is, “Does Adrien Dumont de Chassart have a girlfriend?” The answer is yes.

Their relationship isn’t just a low-key affair—it’s one that Adrien occasionally showcases on social media.
While Adrien keeps much of his private life relatively guarded, he doesn’t hesitate to share glimpses of his time with Katie through Instagram posts and stories.
Katie Underwood comes from a family that understands the demands of elite sports. Her father is Brad Underwood, the respected head coach of the University of Illinois men’s basketball team.
This sports-oriented upbringing likely adds a unique dimension to Katie and Adrien’s relationship, as both understand the dedication and pressures that come with being part of competitive athletics.

While Adrien doesn’t flood his profile with relationship content, the glimpses he shares are enough to show his admiration and love for Katie.
The Family Connection: Brad Underwood’s Influence
Katie’s father, Brad Underwood, is a prominent figure in American college basketball. As the head coach of the University of Illinois men’s basketball team, Brad Underwood is no stranger to media attention and the highs and lows of competitive sports.
Having a father in such a high-profile position may have influenced Katie’s understanding of fame, discipline, and balance—traits that she likely brings into her relationship with Adrien.
It’s interesting to think about the dynamics between Adrien and Brad. While Brad comes from a basketball background and Adrien from golf, both worlds require extreme dedication, time management, and mental toughness.
It wouldn’t be surprising if Adrien found a source of inspiration or guidance from someone like Brad Underwood, who has decades of experience managing athletes and dealing with high-pressure situations.
