Following a career as a National Hunt jockey, John Quinn began training in the 1990s, firstly from Bellwood Cottage, and now from Highfield Stables as well, both in Malton, North Yorkshire. In that time, John’s training career has gone from strength to strength, and in 2022 the yard broke through the £1 million prize money mark in the UK for the first time, alongside almost £500,000 won overseas, much of it thanks to the star sprinter Highfield Princess, winner of three Group 1s. In January this year, John's Son, Sean Quinn, officially joined his dad's training licence after being his assistant for the past eight years.
