Trainers
Ashleigh Stewart
Ashleigh grew up riding with Fran and Joe Dotoli in Massachusetts, where she developed a strong foundation in the hunters and equitation and built an extensive junior career. After starting her family, she transitioned into a professional career as a trainer and rider, successfully competing and producing horses in both the hunters and jumpers up to the highest levels.
For the past 18 years, her program at Redwood Farm LLC has been dedicated to developing accomplished horses and riders across the Hunters, Jumpers, and Equitation. Ashleigh has guided students and young horses to major championships, including USEF Pony Finals, USEF Medal Finals, ASPCA Maclay Finals, Ariat Finals, NEEC Finals, USET Finals, and more.
A true horsewoman, Ashleigh brings deep experience, technical knowledge, and a hands-on, detail-oriented approach to every horse and rider she works with. Her commitment to thoughtful development, strong horsemanship, and long-term success is at the heart of Redwood Farm’s training philosophy.
Hayden Stewart
Hayden followed in her mother’s footsteps, developing a passion for horses from a young age. She built an accomplished junior career training with her mom, Ashleigh Stewart, beginning in the pony divisions and progressing into the equitation ranks. As she advanced, she continued her development with additional guidance from Val Renihan.
She earned top placings in the Big Eq at many major venues on the east coast circuit. In 2016, she finished inside the Top 25 at both the USEF Medal Finals and the ASPCA Maclay Finals. Her junior career continued to grow in the jumper ring, where she successfully competed in the High Junior Jumpers and at the national grand prix level. She was then recruited to ride for the Texas A&M Equestrian Team, earning starting positions in both Flat and Fences.
Now back in the sport professionally, Hayden brings her experience, feel, and thoughtful approach to developing the next generation of horses and riders.
Debbie Seymour
With more than 35 years of experience in the hunter/jumper industry, Debbie began her training career at Westbridge Equestrian before co-founding Bit by Bit Farms in 2002. She has since built a respected freelance training program grounded in thoughtful horsemanship, clear communication, and a genuine passion for developing riders.
She has successfully coached riders to Pony Finals and Junior Hunter Finals, and she has guided many others who simply want to strengthen their skills and confidence. Debbie has worked alongside top trainers and riders at premier show facilities, experiences that continue to shape and elevate her approach.
Debbie's mission is to help each rider build a healthy and lasting partnership with their horse, one that supports growth both in and out of the saddle.
