Biography

Dr. Randolph Winter received his DVM degree from Texas A&M University College of Veterinary Medicine and Biomedical Sciences in 2010. He then completed a rotating internship in Small Animal Medicine and Surgery at Colorado State University. Afterwards he returned to Texas A&M to complete his Cardiology Residency, and he became a Diplomat of the American College of Veterinary Internal Medicine, subspecialty Cardiology, in 2014.

Dr. Winter then became a faculty member in Cardiology at Auburn University College of Veterinary Medicine from 2014 – 2018, during which time he completed a PhD degree in Biomedical Science. From 2019-2021, Dr. Winter was a faculty member at Ohio State University College of Veterinary Medicine.

Previous honors and awards that Dr. Winter has received include: Outstanding Small Animal Intern in 2011, ACVIM Resident Research Award in 2014, and SAVMA Teacher of the Year in 2018.

He has returned to head the Cardiology service here at Auburn University.
