Anna Jane White-Mullin began riding when she was five years old and was "discovered" by George Morris when she was eleven. Competing in major horse shows on the East Coast, Ms. White-Mullin won junior hunter and equitation championships at many noteworthy shows, including Ox Ridge, Fairfield, Harrisburg, Washington, Madison Square Garden, and the Florida Circuit shows. In 1971, coached by Ronnie Mutch, she won the Alfred B. Maclay Finals on her horse, Rivet, and was awarded a gold medal for winning 20 USEF Show Jumping Talent Search Classes. After graduating from Randolph-Macon Woman's College, Ms. White-Mullin continued her equestrian activities as a Registered (Big "R") judge in the hunter, hunter seat equitation, and jumper divisions. In 1986, she was a panelist at U.S. Equestrian's Hunter Seat Equitation Judges Clinic in San Francisco, presenting a slide show based on her book, Judging Hunters and Hunter Seat Equitation. Subsequently, these slides were added to the permanent files of U.S. Equestrian. She is also the author of Winning: A Training and Showing Guide for Hunter Seat Riders and The Complete Guide to Hunter Seat Training, Showing, and Judging.
