individually and the team took fourth. At the 1994 World Equestrian Games, he placed 44th individually riding On a Mission and again acted as an alternate for the US team. O'Connor competed in two Olympic Games for the United States. At the 1996 Summer Olympics in Atlanta, Georgia, he took fifth place individually, riding Custom Made. Riding a second horse, Giltedge, he also helped the US team to a silver medal. At the 2000 Summer Olympics, again riding Custom Made, he took the gold medal, and helped the US team to a bronze aboard Giltedge. During the individual competition at the 2000 Games, he led each stage of the event, and made Olympic history with a record-breaking dressage score. Observers called the ride "accurate and precise with good cadence throughout." At the 1997 Badminton Horse Trials, O'Connor and Custom Made won the CCI4*, the top event at the trials, becoming only the second American pair to do so. In the 1998 World Equestrian Games, O'Connor, riding Giltedge, took an individual sixth place and helped the US team to a fourth place. Again riding Giltedge, O'Connor won silver at the 1999 Pan American Games and assisted the US team to a gold medal. The pair also rode to a team gold at the 2002 World Equestrian Games in Jerez, Spain. O'Connor was consistently ranked as one of the top three day event riders in the world by the Fédération Équestre Internationale, holding fourth place in 1996, third place in 1997 and first place in 2000. He was also the top eventing rider in the US, topping the United States Eventing Association (USEA) leaderboard, in 1998 and 1999. He was a three-time winner of the Rolex Kentucky Three Day, once at the CCI4* level and twice at the CCI3* level. Administrative career In 2002, both Custom Made and Giltedge were retired from competition. In 2004, O'Connor retired from competition and quickly became involved in administrative aspects of the three-day eventing world. He served as the President of the United States Equestrian Federation from 2004 to 2012. In 2006, O'Connor was appointed the International Technical Advisor to the Canadian national eventing team. In that capacity, he led the team to silver medals at the 2007 Pan American Games and the 2010 World Equestrian Games. In January 2013, O'Connor left the Canadian team after being appointed chef d'équipe to the US national eventing team.
