Diane's passion for horses began at a young age in Bogota, Colombia where she grew up . After being caught several times, disguised as a boy, roaming the mountains in search of horses to go galloping on, with nothing but a bit of twine in her pocket , her mother decided to find her some “proper” riding instruction! Diane graduated with a Masters in Architecture and after starting her architectural practice in the late 70's she immediately returned to her childhood passion . For the next 6 years she traveled through the United States and Europe taking instruction from trainers she considered masters and mentors.

In 1985 she moved to Utah attracted by the vast amount of open space available to ride her horses freely. She started and trained horses in the deserts and mountains of Utah accompanied by her 3 children ages 2-4 and 8 who fortunately had inherited her same passion. In 1986 she built Tally Ho Farm, an 11 acre equestrian facility in Park City, Utah . There she continued developing her training philosophy based on the schools of classical dressage: Cadre Noir, The Spanish Riding School, The Royal Andalusian School of Equestrian Art and the Portuguese School of Equestrian Art. Diane also continued developing riders and horses in dressage and eventing. She pursued dressage through the FEI level, competing and training successfully on a national level.

In 2002 Diane rediscovered the Iberian horse and “philosophy and practice” were finally melded. She continues instructing and training in the art of Classical dressage and showcases her Lusitano Stallion Xantel and her Lusitano Mare Afrodite , both trained through level 4... (Grand Prix) Through her affiliate business “Placido Dressage” Diane and her business partner Sheri Prucka now breed, train and sell Lusitano and PRE horses and stand Diane's stallion Xantel Interagro.

As an extension to the principals of riding in lightness, and in their commitment to help grow the exciting new equestrian sport of Working Equitation, Tally Ho Farm has joined with “Working Equitation International Association, USA “ as their Utah Affiliate. Through clinics and private instruction Diane combines Working Equitation and classical dressage. People of all riding levels are truly enjoy the basics of dressage in a fun and exciting way.
