Claire Diamond
Claire has been passionate about horses her entire life, but began competing seriously eight years ago. She lives in Sandy, Utah, and trains at her family’s facility, Diamond Equestrian Center. Claire competes in Hunters, Jumpers, and Equitation, and currently shows her two horses in the junior jumper divisions. This year, her goals include returning to the North American Youth Championships and qualifying for the Youth Nations Cup in Belgium.

Dane Anson
Dane Anson is a 15-year-old junior rider from Vancouver, Canada, who has a passion for his horses and supporting his fellow riders. Competing in hunters, equitation, and derbies, Dane trains under the guidance of Archie Cox and Karli Postel at Brookway Stables while showing in the U.S. and with Eliza Hunt of Obsidian Stables during competitions at Thunderbird Show Park in Canada.

Katherine Leaffer
Born and raised in Colorado, I grew up riding out of smaller barns with limited access to horses and show opportunities. Once I got my license, I began showing more competitively on the Colorado circuit, occasionally traveling to shows throughout the region and in California. In high school, I spent countless hours grooming and doing barn chores in exchange for riding time and experience, driven by a desire to understand every aspect of the industry—a mindset I still carry with me today.
Eager to expand my horizons, I moved to San Diego after graduating and enrolled at San Diego State University. But my passion for high-level sport quickly drew me to the Wellington circuit, and at 19, I relocated across the country to immerse myself fully in the industry. I’ve been based in Wellington ever since and joined Alex Granato’s program in September 2024, where I immediately connected with his philosophy and approach to horsemanship. Outside the barn, I’m pursuing an online degree in Finance with a concentration in Real Estate. When I’m not working with horses, you’ll find me exploring the outdoors, flowing through a yoga class, or experimenting in the kitchen.
At the heart of everything I do is a deep love for the horses—their presence is grounding, and building meaningful partnerships with them is what drives me every day.

Evie Becky
Evie Becky rides with Bridgeport Farms both in the Hunters and in Equitation. She finished 2024 in 3rd Place Nationally for Horse of the Year and was awarded Champion of Children’s Hunter 14-17 by PCHA. Most recently, she earned Circuit Champion and Circuit Reserve Champion at the Desert International Horse Park for the 2025 Circuit.
In addition to her passion for riding, Evie is a dedicated student and maintains a 4.0 GPA, including several honors courses. She is proud of her young accomplishments in philanthropy, having raised tens of thousands of dollars for St. Jude's Children's Hospital, One Voice and The Pug Queen Foundation. As a life-long resident of Pacific Palisades, Evie and her family and friends were deeply impacted by the Palisades fire. Her most recent fundraising effort was the creation of a special #palistrong bracelet which was sold by her jewelry company, Jewelz by Eves. This fundraising effort earned thousands and benefited the LAFD and victims of the fire.
Evie is a proud Gilly’s Magic Muffins ambassador and her horses are always happy to try the new creations!

Slate Mellencamp
Hi, I’m Slate Mellencamp and I’m from Los Angeles, California. I ride with Frontier Farms and Angel Karolyi LLC. I have two horses, one named Classy and the other named Nina. I show Classy in the 1.30 Junior Jumpers and I show Nina in the 3’6 younger Juniors hunters. My favorite flavor of GMM is Scope! Nina and Classy absolutely love this flavor because of its big gum drop in the middle.
