Since he eastablished his bloodstock agency in 1978 with his wife Anna, Peter and his team have enjoyed remarkable success around the world. Their son Ross joined the agency in 2001 becoming the third generation of Bloodstock agents in the family.
Peter himself is modest about his achievements, but published statistical surveys in some of the most respected industry journals show that his judgement places him firmly at the top of his profession.

Background
Peter and Ross have a family background steeped in racing. The late Jack Doyle Peter's father and Ross's grandfather was described as "the doyen of bloodstock agents" and for some 60 years was a major force in the industry. When Peter was working with his father, yearling purchases included Classic Winner Bruni and European Champion Sprinter Sandford Lad.
 
Early Days
The agency had the good fortune to team up with the leading Irish trainer Liam Browne and the partnership had a dream start with the 1982 classic winner Dara Monarch. The colt won the Irish 2000 Guineas and confirmed his status as the leading European miler by winning the St. James Palace Stakes at Royal Ascot.Winning Partnership  
The most successful bloodstock agent/trainer partnership in racing in the past 20 years has been that of Peter Doyle and champion handler Richard Hannon. A host of group winners have been purchased for satisfied owners. A special niche has been carved by the team in the valuable sales related races and the pair have compiled an enviable record in races such as the Tattersalls Breeders Stakes, the Goffs Challenge and the Weatherbys Super Sprint.
 
International Recognition
The agency then linked up with one of the most successful racing entities in France, the de Moussac family, owners of the Haras de Mezeray. Purchases for the family, all trained by champion handler Andre Fabre, include such luminaries as Homme de Loi, Pigeon Voyageur, Boromini and Savoureuse Lady. Scandinavia has also proven to be a fertile area for the agency and nothing exemplifies their success in the region as the association with top trainer Wido Neuroth. Valley Chapel, the Derby winner in Norway, Sweden and Denmark in 1999 was a highlight while Kill The Crab repaid her investment by winning more than £250,000 sterling and a string of group races.
