Aubrey Adler - Riding Assistant

Riding assistant Aubrey Adler has been with us since 2018. She is wonderful with youngsters (horses and people). Aubrey has been riding since she was 4 years old. Over the years she has trained in a variety of disciplines including dressage, hunter/jumper, 3 day eventing, drill team, huntseat and western equitation and pleasure. She even dabbled in driving, gaming and vaulting. At age 8 her mom helped start a riding school in Redmond. Aubrey and her sister grew up caring for the horses and riding as much as possible. Soon they were riding with various other local trainers gaining skills and versatility on a wide variety of horses and ponies. Aubrey's somewhat eclectic background gives her a wide base of understanding that she brings to her training. Currently she is showing the Welsh mare Duet to Pony Cup wins and national All Breed awards in dressage. Her size and expertise is perfect for ponies and young horses. She is helping to compete the youngsters here at Derby Farms and in 2019 she earned her USDF Bronze Medal on Bonnie Kearney's Rodio and our foundation sire Rodioso.
