JOLYN Welcomes Olympic Silver Medalist Katie Grimes as Exclusive Training Partner
HUNTINGTON BEACH, Calif. (March 2026) — JOLYN is proud to announce that the brand has been named the exclusive training partner of Olympic and World Champion swimmer Katie Grimes, marking a new chapter between one of swimming’s fastest-rising stars and a brand built for athletes who live in the water.
An Olympic silver medalist and World Champion, Grimes has quickly established herself as one of the most versatile swimmers in the world, competing across distance freestyle, individual medley, and open water events. She first captured global attention at just 15 years old as the youngest member of Team USA at the 2020 Summer Olympics and went on to earn a silver medal in the 400m individual medley at the 2024 Summer Olympics. She is also a member of the five-time NCAA champion University of Virginia women’s swim team and an All-American swimmer. As her exclusive training partner, JOLYN will support Grimes throughout her training while collaborating with her on products, content, and initiatives that celebrate the next generation of swimmers.

“JOLYN has always been a brand made for swimmers who put in the work every day,” said Grimes. “I love that the suits are built to perform through long practices and tough sets while still feeling fun and expressive. I’m excited to partner with a brand that understands swimmers and the lifestyle around the sport.”
Born on a lifeguard stand and rooted in the swim community, JOLYN has spent over a decade designing performance swimwear trusted by elite athletes, lifeguards, and everyday swimmers alike. Grimes’ relentless training style and passion for the sport make her a natural fit for the brand.
“Katie represents everything JOLYN stands for—dedication, authenticity, and a love for the water,” said Mondy Herndon, CEO at JOLYN. “She’s one of the most exciting athletes in swimming today, and we’re thrilled to support her as she continues to push the limits of the sport. As a former swimmer at the University of Virginia, it’s extra special for me that we share the same alma mater, and I’m thrilled to see Katie continue the tradition of excellence at UVA in and out of the water.”
Through the partnership, Grimes will train exclusively in JOLYN suits and will be featured across JOLYN campaigns and initiatives.
