Michael Hewetson graduated from Onderstepoort, South Africa in 1999. He spent a year in private equine practice before completing a residency in equine internal medicine, critical care and anaesthesia at the University of Glasgow. He holds the RCVS certificate in equine internal medicine and is a diplomate of the European College of Veterinary Surgeons. He currently works as a senior lecturer in equine internal medicine at the Royal Veterinary College.
