Allison Brock, riding Rosevelt, was a member of the bronze medal-winning U.S. Dressage Team at the 2016 Olympics in Rio de Janeiro—the first time the U.S. Dressage Team had won an Olympic medal since 2004. She also is a United States Dressage Federation gold and silver medalist.

Brock’s major victories with Rosevelt include winning the 2014 CDI3* Grand Prix and Grand Prix Special at Dressage at Devon; the 2015 CDI-W Grand Prix and CDI3* Grand Prix at the Adequan Global Dressage Festival 1 and the Adequan Global Dressage Festival 7, respectively, and earning a team gold at the Stillpoint Farm Nations Cup CDIO3*; and the CDI4* Grand Prix Special and CDI3* Grand Prix and Grand Prix Special at the Adequan Global Dressage Festival 12.

Brock is based in Keswick, Virginia, and Wellington, Florida. The Hawaii native has done it all: before becoming an Olympic dressage competitor, she also show-jumped, rode Western, and was active in her Pony Club. She moved to the mainland at age 17 to pursue her dressage career.
