Prior to attending veterinary school at the University of Wisconsin he worked in a veterinary emergency hospital for four years. While in veterinary school, he was awarded scholarships for his insights into geriatric medicine and nutrition as they pertain to patients in the critical care unit. His clinical year brought him to specialty practices in California and Michigan where he trained under board certified emergency and critical care clinicians. He was subsequently acknowledged by the Veterinary Emergency and Critical Care Society (VECCS) for outstanding achievement. After graduation in 2004 he worked in general practice before working in emergency hospitals in both Madison, WI and McHenry county IL. Dr. Thrall then joined the veterinary team at the AEC in 2007, and became the Medical Director in 2008. He has been a member of the Veterinary Emergency and Critical Care Society since 2000 and the American Veterinary Medical Association since 2004. His other interests include spending time with his children, camping and feeding his chickens and sheep, as well as restoring a 1947 Ford 8n tractor.
