Ronan qualified from the RVC many years ago and worked for several years in mixed and small animal practice before moving to the veterinary pharmaceutical industry as a member of a Technical Services team. He held a succession of roles, initially as part of the UK team but subsequently as part of a team providing global technical support to colleagues across the world. In 2024, he joined Protexin Veterinary where he has developed an interest in the importance of the gut microbiome, its role in overall wellbeing and the consequences of dysbiosis in both animals and humans.
