Peter Gregory qualified at Bristol University Veterinary School (UK) in 1972 and worked in mixed practice in Yorkshire and then Queensland (Australia) for several years, before returning to UK in 1984 and discovering homeopathy. Ever since then he has practised homeopathy, mainly for small animals, but also for other species when requested to do so. In 1995 he set up a referral practice in Staffordshire and in the same year started lecturing with the Homeopathic Professionals Teaching Group in Oxford. Since then he has lectured on veterinary homeopathy extensively, both in UK and in many other countries. In 2000, to allow sufficient time for teaching he joined Tim Couzens in the Holistic Veterinary Medicine Centre, in Sussex, until retiring to Wales in 2021. He is a Fellow, and Veterinary Dean, of the Faculty of Homeopathy in London, and an ex-president of the British Association of Homeopathic Veterinary Surgeons and the International Association for Veterinary Homeopathy. He is author of ‘Insights into Veterinary Homeopathy’, and has contributed to several other publications.
