Originally from the Milwaukee, Wisconsin area and born November 20, 1963, Elizabeth “Beezie” Madden received her first pony as a Christmas gift. She began competing at the Grand Prix level in 1985. Horses have been a family affair for Madden; her parents, Joe and Kathy Patton, owned a horse farm in Wisconsin, and for Beezie and her husband John, they operate their stable, John Madden Sales, in Cazenovia, New York.

Madden has set the standards for show jumping in many ways. She was the first woman to pass the $1 million mark in earnings for show jumping. In 2004 she became the first woman and the first American rider to reach the top three in the Show Jumping world-ranking list. Madden is also the only four time USEF Equestrian of the Year.
