Peter was born in Ireland and spent a majority of his youth attending the races with his mentor and leading racing journalist Tom McCormack.
On leaving school Peter went to Kentucky where he worked for the leading farm Taylor Made. He also spent time working for Windfield’s Farm in both Canada and Maryland (home of the famed Northern Dancer). Following this Peter worked in the Southern Hemisphere seasons in Australia handling the Coolmore stallions at Arrowfield Stud, Woodlands Stud, Stockwell Stud and Ra Ora stud in New Zealand. He also spent invaluable time with leading trainers Colin Hayes at Lindsay Park and Neville Begg in Sydney.
Peter worked at Coolmore Stud for over 25 years working within all aspects of one of the worlds largest breeding operations. In 1996 he moved permanently to Australia to take over the management of Coolmore Australia before starting work at Segenhoe Stud in 2014.
