Jamie Wignall, BVetMed (Hons), MS, Diplomate ACVS

 

Dr. Wignall comes from a family of veterinarians in the United Kingdom, and after pursuing veterinary school at the Royal Veterinary College in London, he returned home for a year in rural mixed animal practice. Adventure beckoned, and he completed his surgical training at Louisiana State University where he found a southern girl, a love for the New Orleans Saints and a terrier called Maverick. He then worked in Southern California for 4 years where the family expanded to add two more terriers, Biffy and Ziggy. His hobbies include snowboarding, soccer, hiking and spending time with his partner, Luli, also a veterinarian.

His professional interests cover all aspects of orthopedics, soft tissue, and neurosurgery, with a particular emphasis on the upper airway and minimally invasive surgery. Practice management has become a new interest and he is studying towards a Masters in Business Administration.
