Simon Tappin


Clinical Director


  • European and RCVS-Recognised Specialist in Small Animal Internal Medicine
  • Honorary Associate Professor, University of Nottingham

Simon trained at the University of Cambridge and, after qualifying, spent 2 years in small animal practice before taking up a Residency in Small Animal Medicine and Intensive Care at the University of Bristol. He joined DWR in 2007. He holds the Royal College Certificate in Small Animal Medicine and the European Diploma in Veterinary Internal Medicine. He is an active member of the British Small Animal Veterinary Association and was editor of their Companion Journal for 5 years. Simon particularly enjoys critical care and has been instrumental in developing the Interventional Radiology service at DWR, using minimally invasive techniques and bio-materials to treat many conditions which previously required more invasive surgery. He has lectured widely in the UK and Europe on subjects including emergency medicine and interventional radiology.
