The Surprising Shift from NHL Star Andreas Athanasiou

For years, the public knew Nelly Korda's partner to be Canadian ice hockey professional Andreas Athanasiou.

Athanasiou, known for his speed and skill in the National Hockey League (NHL), was a fixture in Korda’s personal life for a significant period.

The transition to Casey Gunderson was kept remarkably quiet, which is not surprising given Korda's preference for privacy regarding her personal relationships.

The Athletic Connection: Division I Football

While Gunderson is not a professional athlete today, he shares a crucial common ground with Korda: a history of elite-level athletic competition. He was a Division 1 American Football player during his college years at Bryant University. This athletic pedigree means he understands the dedication, sacrifice, and mental toughness required to compete at the highest level.

This shared experience—even in different sports—is a powerful foundation for their relationship. He can relate to the highs and lows of competition, the "grind" of a professional season, and the need for unwavering support, all while maintaining his own successful career.

The Engagement: A Personal Triumph After a Challenging 2025 Season

The timing of the engagement announcement in late November 2025 is particularly poignant. It occurred just days after the conclusion of the LPGA's season finale, the CME Group Tour Championship.

The 2025 LPGA season was widely described in the media as a "grind" for Nelly Korda. Despite her immense talent and previous historic success, the year was marked by a "mix of highs and lows" and, notably, Korda went "winless" in the season. She faced immense pressure as a former World No. 1 and Olympic gold medalist.

The Engagement as a Personal High:

The surprise engagement to Casey Gunderson served as a massive, positive counterpoint to a difficult professional year. It provided a huge personal triumph and a moment of joy right as the professional pressures subsided for the off-season. The announcement was made with a series of sweet photos on Instagram, confirming her happiness and new relationship status.

Adding to the excitement, the news came just after her brother, Sebastian Korda, a rising star on the ATP Tour, also announced his engagement. This double dose of good news solidified the Korda family’s reputation for both athletic excellence and headline-making personal milestones.

The Korda Dynasty and Future Wedding Plans

Nelly Korda is part of one of the world's most famous sports families. Her father, Petr Korda, is a Grand Slam-winning tennis champion, and her brother, Sebastian Korda, is a top-ranked tennis player. Her sister, Jessica Korda, is also a highly successful LPGA golfer.

Casey Gunderson's integration into this dynasty is a testament to his character and the strength of his bond with Nelly. While details about the wedding remain private, the event is expected to be a major social occasion, uniting the worlds of professional golf, tennis, and business. The focus now shifts from "Who is Nelly Korda's boyfriend in 2025?" to when the Korda-Gunderson wedding will take place, marking a beautiful start to her personal life in 2026 and beyond.
