Family of Equestrians

Heidi Cowley, Owner/Trainer

It was love at first sight for Heidi and horses. Once her parents conceded their daughter's love of horses, there was no turning back. Within a couple of weeks of starting lessons, they owned their first horse. During her junior years, she qualified for twenty Medal Finals,  and won the Norcal Medal Finals. Grabbing the eyes of Bertalan de Nemethy, coach of the Olympic Team, Heidi was invited to ride with the US team in Gladstone, NJ.  She then moved to Los Angeles to join Marcia Williams (2007 Show Jumping Hall of Fame inductee and USEF living Legend honoree, Show Hunter Hall of Fame inductee). Together, they produced numerous champions in both the hunter and jumper divisions in Southern California, and won many PCHA and AHSA Year-End Championships. After getting married,  Heidi established her own business in British Columbia.  She then returned to Northern California in 1984 where she started Boundary Gate. The Cowley family has resided at Boundary Gate where they have raised their own family as well as being a part of countless other families through the friendships the "barn" has fostered. Heidi continues to pursue her passion to teach and train riders and horses to be the best that they can be.

Jamie Cheney, Owner/Trainer

Always at the heels of her mum, Jamie grew up as part of the horse world. Riding competitively in the pony divisions on her own "Shrimp on the Bobby" and "Kooralynn Twinkle" and catching rides on top sale ponies, she logged many miles in the hunter ring. With successful years in all of the Junior hunter and Medal classes and finals, Jamie won the Pickwick Medal finals in 1999. With immense gratitude to Marcia "Mousie" Williams, Jamie was united with "Sharp Try" in 1997. "Digger", as he was lovingly known, was that special horse that allowed Jamie to compete in and win the High Junior Jumper divisions winning Championship at HITS Desert Circuit, Menlo Charity Horse Show, and countless others to finish off her Junior years. Jamie graduated from University of Oregon with a degree in Human Physiology in 2006. After marrying and having two beautiful daughters, Jamie has returned to Boundary Gate and joined her mother.  As a professional, she loves to bring along young horses and has found her way back to the world of ponies through breeding and developing ponies for her daughters.
