Susan Treabess was born without her left hand, but has ridden horses her whole life. She has been competitive in dressage since she was 16, and became involved in international para-equestrian dressage in 2006.
Treabess began riding the KWPN mare, Moneypenny, in 2008. They swept each of their divisions at the 2010 Dressage Affaire FEI CPEDI3* and won the overall highpoint award.
Treabess and Moneypenny also competed at the Prix St. Georges level in able-bodied dressage shows during the 2010 season. They have already been successful at Third and Fourth levels, ranking nationally at both for the past two years.
At the USEF Selection Trial/National Championship for the U.S. Para-Equestrian Team for the 2010 Alltech FEI World Equestrian Games held in June, Treabess and Moneypenny claimed fifth-place honors.
The pair finished their 2010 season by competing on the U.S. team at the Alltech FEI World Equestrian Games.
In 2012, Treabess returned to the ring on Fugitivo XII where the two finished second and third, respectively, in the CPEDI FEI Grade IV KUR and Grade IV Individual Championship Test.
At the 2014 USEF Para-Equestrian Dressage National Championship, Treabess finished in fifth place with the PRE stallion Kamiakin.
