Sue Dyson qualified as a veterinarian from the University of Cambridge in 1980. After an internship at the University of Pennsylvania and a year in private equine practice in Pennsylvania, Sue returned to Great Britain to the Animal Health Trust, Newmarket. Sue ran a clinical referral service for lameness and poor performance, attracting clients from all over the United Kingdom, Ireland and continental Europe for 37 years. From 2019 she has worked as an independent consultant, combining her horsemanship skills with her previous veterinary experience, with the aim of maximising performance potential. Sue's key interests are improving the diagnosis of lameness and poor performance and maximising the opportunity for horses to fulfil their athletic potential at whatever level, taking a holistic approach to the horse, rider and tack combination, and improving approaches to diagnosis and management. She has been involved not only in providing clinical services, but also clinically relevant research and education. Sue is co-editor, with Mike Ross, of Diagnosis and Management of Lameness in the Horse and co-author of Clinical Radiology of the Horse and Equine Scintigraphy. She has published more than 400 papers in peer reviewed journals concerning lameness and diagnostic imaging and has lectured worldwide to veterinarians, paraprofessionals, coaches, riders and judges. Sue is a former President of the British Equine Veterinary Association and is currently scientific advisor to the Saddle Research Trust and Moorcroft Rehabilitation Centre. Sue is also a rider, and has produced horses from novice to top national level in both eventing and show jumping. Sue holds the Instructors and Stable Managers Certificates of the British Horse Society (BHSI).
