I have been in Grangemore stud since 2014 married to Serena. We hope to breed and sell precocious racehorses that are tough, sound and genuine.

Great success for all of the team at home, especially Ollie who rides her everyday - ridiculous price considering how she flew in the final furlong at Fairyhouse Thanks to owner breeder @guy_oc for giving the yard the opportunity with such a well bred filly
