Adrian was born on May 10, 1965 in Oxford, England. His family still lives in Wantage, a small town within a huge racing community set beneath the rolling downs of Berkshire and Oxfordshire. It is the home of some of the top racehorses in the U.K.
Adrian started working with racehorses at age 11. At 16 he started full-time with John Dunlop and attended the Jockey Apprentice School at Goodwood. From there he moved back to Wantage and worked for Captain Forster. During this time, Adrian looked after 1985 Grand National winner, Last Suspect. It was here that he first met Graham who had traveled from America with a horse for Jonathan Sheppard.
They met again when Adrian moved to the United States in 1989 to work and ride races for Jonathan Sheppard and later worked for Graham when he was assistant to Bernie Bond. When Bernie retired, Graham took out his license and Adrian stayed to become Graham’s assistant and right-hand man.
