Susan is one of the most successful dog agility competitors of the last decade. Since winning her first USDAA Grand Prix Final in 1996 with her Border Collie ”Stoni,” Susan has accumulated a total of 16 National and International Championship wins covering 7 different jump heights (8”, 10”, 12”, 16”, 22”, 24” & 26”) and has won two height divisions at a National Agility Championship on three different occasions. In total her dogs have over 50 top ten placements at National Championships including 14 First Place finishes and 6 Second Place finishes. Stoni (1990-2005) is still the only dog in history ever to win the USDAA "Triple Crown" (Grand Prix, Steeplechase, and DAM Team National Championship). In addition, Susan and her mixed breed dog “DeCaff” won the Gold Medal at the 2005 ESPN Great Outdoor Games. Every dog Susan has ever owned has won at least two National or World Championships. Susan and DeCaff kicked off the 2006 season by winning the Individual All Around and Biathlon Gold Medals at the IFCS World Championships held in Oosterhout (Netherlands).

Susan brings over thirty-five years of experience from the world of show jumping. A lifelong horsewoman, she has ridden for many years with some of the nation's most noted horsemen including Gene Lewis, George Morris and the late Jimmy Williams and has competed throughout the United States and Canada. Turning professional, she moved to the East and spent sixteen years between New Hampshire and Virginia helping clients achieve their goals.

Susan brings her extensive experience of combining speed with jumping to the sport of Agility. She offers a unique perspective and knowledge of the mechanical aspects of jumping which when properly applied can create muscle memory and balance for the canine athlete. Not to be confused with a handling seminar, her lessons and workshops focus entirely on the dog and build better jumping skills and instill more confidence and speed. Training with Susan is an opportunity for you to develop your 'eye' and witness your dog learning about balance, striding and scope until jumping becomes effortless.

Susan trains both horses and dogs at her residence in Northern California where she lives with her brilliant Jack Russell Terrier, Patrick.
