Sam Beeson, DVM, PhD, DACVIM (Oncology), is an assistant professor in the University of Illinois College of Veterinary Medicine’s oncology service, according to a faculty spotlight published October 2, 2026. His path to veterinary oncology began with a very different plan: he entered veterinary school expecting to become an equine ambulatory veterinarian, then changed direction during a fourth-year oncology rotation.
Education and veterinary training
Beeson grew up in Minnesota and earned his bachelor’s, DVM, and PhD degrees at the University of Minnesota, according to the University of Illinois College of Veterinary Medicine’s October 2, 2026, faculty spotlight.
He then completed a small-animal rotating internship at North Carolina State University, followed by a medical-oncology residency at Colorado State University. The spotlight identifies him as an assistant professor in the University of Illinois College of Veterinary Medicine’s oncology service as of its publication date.
How Beeson chose veterinary oncology
Beeson began veterinary school expecting to work as an equine ambulatory veterinarian. During an oncology rotation in spring 2020, his plans changed: he decided oncology was the career he wanted and shifted his remaining rotations toward the small-animal hospital.
