Four years of continued success followed, which included participation on winning U.S. Nations Cup teams, which led to her being named the 1989 United States Olympic Committee's Female Equestrian of the Year. So far in 2006, Madden has had multiple successful rides including her role in the Samsung Super League tour as part of the U.S. Team that finished second in the Nations Cup in Aachen, aboard Authentic. In the past few years, Madden has been a critical member of the United States Teams. Riding in six out of the eight competitions, she anchored the team for the 2005 Samsung Super League which the U.S., the only non-European team competing in the League, decisively won. Also in 2005, she won the million dollar CN International at Spruce Meadows in Canada on Judgement, and won the $200,000 American Invitational in Tampa, Florida, on Authentic. In 2004, she breezed through the Olympic Selection Trials finishing in first place on Authentic with only eight faults accumulated for all six selection events. With her contribution of double clear rounds in the Athens Olympic Games, she helped the U.S. Team win the Gold medal, while her success on U.S. soil earned her the American Grand Prix Association (AGA) Rider of the Year title in 2004. At the 2003 Pan American Games in the Dominican Republic, she was a member of the Gold medal U.S. team.

Over the years, other laurels include the 1997 Rolex/USET Show Jumping Championship and the AGA title that year; the Mercedes German Masters and the Audi Grand Prix in 2003; and many, many more prestigious wins in both the United States and Europe.
