Australian by birth, Phillip moved to the United States in 1991 to train in a more internationally competitive environment, and to prepare for the 1996 Olympics in Atlanta as a member of Australia’s gold medal three-day eventing team. Since his move to the U.S., Phillip has represented Australia in three Olympics and four World Championships.

In 2006, Phillip became an American citizen to represent his adoptive home in international competition. Continuing his winning ways, he was a member of the US team for the first time at the Pan American Games in Rio de Janiero in July 2007, where his performance earned team gold and individual silver medals.

He is very active on the U.S. eventing circuit, winning the USEA Leading Rider of the Year title in 1998, and 2000, 2001, 2002, 2003, 2004, 2005, 2006 and 2007. In 2005 he was also the number one FEI World Event Rider.

Phillip and his wife Evie own, manage and train out of True Prospect Farm, in West Grove, Pennsylvania and at their new Red Oak Farm in Aiken, South Carolina. Phillip dedicates a good deal of his time to coaching other riders. He coached the US Area II Young Riders in 2001 and 2002, and coaches many adult amateurs and a number of the USET short listed riders.
