When the famous show jumper Authentic wants something, he knows who to talk to: Clark Shipley.

“If Authentic is in his stall and wants to go out in the paddock, every time he sees Clark he screams at him. He knows Clark is the one who takes care of him, and Clark makes sure he’s happy,” said grand prix rider Beezie Madden, who rode Authentic to team gold at the 2004 and 2008 Olympic Games, team and individual silver at the 2006 World Equestrian Games, and individual bronze at the 2008 Olympic Games.
