Cathleen Driscoll

I am so excited with the results I have been seeing in my horses since starting them on SummitMax! I truly feel they are moving and jumping better than ever before.

Cathleen Driscoll is one of Team USA’s rising stars in international show jumping, currently representing the U.S. in FEI Nations Cup competitions and climbing the ranks on the FEI Longines World Rankings. She recently helped Team USA to a second-place finish at the Nations Cup in Vilamoura, Portugal, and has been named to the U.S. Jumping Team for the 2025 CSIO3 tour in Denmark and Norway*.

Cathleen began competing in jumpers at age 15 and never looked back. In 2018, she was named the Lindsay Maxwell Charitable Fund/USHJA Emerging Athletes Program national winner, an honor that set the foundation for her professional success. She worked her way up in the industry through Plain Bay Farm, starting as a groom and steadily rising to her current role as head trainer and rider, under the mentorship of Katie and Henri Prudent.

In July 2023, Cathleen dominated the Great Lakes Equestrian Festival in Traverse City, Michigan, capturing Grand Prix wins and topping the Welcome Stakes leaderboard just days apart. She’s now a three-time CSI2* and CSI3* winner in Traverse City alone, riding elite horses like Arome and Magnolia with precision and speed.

What makes Cathleen’s story even more compelling is her late entry into FEI-level show jumping at age 28, defying conventional timelines and proving that perseverance can outshine pedigree. Her background in eventing and her tactical style—like her signature “slice” approach in jump-offs—have earned her respect for both grit and strategy.

Off the course, Cathleen is an advocate for longevity and performance, relying on SummitMax Joint & Mobility IM for Horses to keep her mounts healthy and competition-ready. She credits the supplement for enhancing her horses’ movement, comfort, and jumping ability through long show circuits.

Cathleen is the youngest of three sisters and began her equestrian journey at age five—watching her siblings ride, helping in the barn, and falling in love with the sport. Today, she’s not only a top rider but also a role model for riders who take the road less traveled to success.

We’re proud to support Cathleen as she continues to rise through the ranks of international show jumping—one clear round at a time.
