TAMRA BROWN – Tamra is Anne’s Assistant Trainer. She started out as a working student at Knoll Farm and advanced to the position of head groom for Anne in 1994.

Over the years, Tamra has been given the ride on many talented horses, the majority of whom she trained to the upper levels herself, and several to Grand Prix.  In 2007, she was awarded her USDF Silver Medal. In 2007, she became the Intermediare Champion for Region 8.  In 2009, Tamra was a featured clinician at the Midwest Horse Fair in Wisconsin, one of the largest three-day horse fairs in the country.

Tamra Brown has also successfully shown in CDI competitions.  Her primary partner at the time was the Dutch Warmblood breeding stallion Leoliet (Zioliet x Dorien).  With him, she competed in CDIs in both Prix St. Georges and Intermediare I at Dressage at Devon, Zada Enterprises’ Zada Cup, and the German Equestrian Alliance Cup, a PanAm games qualifier.

After nearly 18 years with Gribbons, who was the USEF Dressage Technical Advisor to the U.S. Dressage team, Tamra has emerged from protege to Gribbons’ assistant trainer and the head of Knoll Dressage’s other trainers, now based in Central Florida.

Tamra is currently active on the Region 3 Florida Show Circuit, coaching several clients in nearly all levels, including FEI, and to earning scores for USDF bronze and silver medals of their own.  Well-rounded and patient, Tamra specializes in producing well-educated and competitive dressage horses as well as inspirational and informative instruction geared toward the understanding of equine mechanics and the blend of dressage art and technique.

Her student, Michelle Sheridan (pictured to the right on her horse Rouxletto), was the Young Rider Intermediare I Champion at the Region 3 USDF Dressage Finals in 2012.



CORINE SMITH – Corine is a life long rider, started riding as a child and went through the pony club, achieving the “A” levels. Corine has been fortunate to experience many different disciplines, including eventing at the FEI junior/young rider level, before switching to Dressage.

Corine enjoys the process of training horses from completely green and unstarted, to the FEI levels, and particularly enjoys riding stallions.  She recently was named the region 3 junior team coach, which won a gold medal at the 2018 NAJYRC, as well as coaching her junior student, Melanie Doughty, to a reserve national championship at Lamplight.

Corine began training with Anne in 2013, and is very pleased to have her training program based out of Knoll Dressage, where she works closely under Anne’s guidance.
