Niki

Clarke

Trainer, Peridot Equestrian

Niki Clarke originally began her riding career as a Three-day Eventer. Early on, Niki trained with Three-Day Eventing greats Amy Barrington and David and Karen O’Connor. Her passion for horses and hard work ethic lead Niki to numerous Eventing accolades at a young age, including being long listed for the Sydney Olympics.

In 2004 Niki decided to make a career change and began her path up the ranks of the Dressage world. She moved to Holland to concentrate on her main love of Dressage, under the instruction of Bert Rutten. In 2005, Niki moved back across the pond to continue her dressage training in the U.S.

In 2006, Niki started Dressage Unlimited a full training barn with an emphasis on developing talented young horses for competition and sales.

Today, Niki is not only a highly respected FEI rider, her career accolades to date include USDF Bronze, Silver and Gold Medals, and a Centerline Scores 5* rated rider. She was Reserve Champion at the Brentina Cup in 2007, third place at the 2010 Brentina Cup, and multiple wins at multiple levels with a variety of horses throughout the FEI levels.

Dawn

White-O'Connor

Trainer, Peridot Equestrian

We are thrilled to announce that the amazing and talented Dawn White-O'Connor has joined us at Peridot Equestrian as trainer! Dawn is one of the rising stars of our sport, and it is such an asset to Peridot to have her knowledge, experience and brilliance here every day.

Dawn, originally from a small town in Colorado, has worked for Steffen and Shannon Peters for over a decade. She began as a working student and groom, but has earned her way to great success in the competition arena.

In 2014, White-O’Connor placed 8th at the Festival of Champions in the Small Tour with Carla Hayes’ KWPN gelding Aristo.

At the age of 27, Dawn was given the opportunity to compete on Steffen's 2016 Olympic mount Legolas, owned by Four Winds Farms Akiko Yamazaki. In 2017, she competed Legolas in CDIs in both California and Wellington, Florida with great success. They won second place during the 2017 World Cup of Las Vegas, right behind Steffen Peters. A few months later they won the Grand Prix and the Special in San Juan Capistrano. They were then selected to represent the The Dutta Corp. U.S. Dressage Team in Grand Prix in Europe that summer.

It was with Legolas that Dawn was first invited onto the USEF Developing Rider list in 2017. Dawn competed Legolas until he was retired in April of 2018.

In 2018, Dawn competed on Four Winds Farms’ 10-year-old Oldenburg gelding, Bailarino (Breitling W—Schila, De Niro). The pair won the 2018 USDF National Developing Grand Prix Championship at Lamplight Equestrian Center in Wayne, Illinois.  That same year, they were also selected as the demo Grand Prix pair for the Isabell Werth Clinic in Encinitas, CA. In 2019, White-O’Connor and Bailarino were selected for the USEF Developing Rider list.

Dawn has a large string of up-and-coming horses that she trains and competes on, and she is often at the top of the leader board at any CDI or national show.

Jessica

Eaves

Mathews

Vice President & Farm Manager, Peridot Equestrian

Jessica wears a lot of hats at Peridot: barn mom, farm manager, lawyer, HR director, cheerleader, decorator, event planner, graphic designer and branding fanatic, construction foreman and poop scooper. Some days, she just calls herself a Gladiator who champions this amazing barn family, the horses and our beautiful facility.

Jessica has been passionate about horses since she was 2 years old, and has been riding since her aunt bought her a horse when she was 8 years old and her parents were away on vacation.

She fell in love with Dressage in her 20s, but didn't really get the time to pursue it until her daughter, Kate, decided she loved it too. There are many days that Jessica thanks her lucky stars her daughter didn't prefer a different sport like soccer. It has given Jessica the chance to fully immerse herself into not only her own passion, but her daughter's.

Jessica is also an amateur rider, who dreams of showing at the FEI level and winning a national championship. For now, she is learning to ride her beloved mare, Gianna (nicknamed Shakira for the sway in her hips) and is loving every minute of being on a horse farm every day. It is a childhood dream come true.
