Chris Thomson

Dr. Chris Thomson is a Diplomate of the American College of Veterinary Surgeons. He is a specialist in veterinary surgery with a particular focus on surgical oncology, minimally invasive surgery, and interventional radiology. Following residency, Dr. Thomson was selected for a fellowship in surgical oncology at the Animal Cancer Center at Colorado State University, the best recognized and longest standing training programs worldwide for veterinary surgical oncology. He has a particular passion for bone cancer, liver and biliary diseases, and urogenital cancers.

Dr. Thomson earned his veterinary doctorate from the University of Minnesota. Following a rotating internship at the University of Wisconsin-Madison, he returned to the University of Minnesota for a residency in small animal surgery. Following residency, he completed the fellowship in surgical oncology at Colorado State University. Dr. Thomson has been on the executive board for the Veterinary Endoscopy Society for three years and is an active member of the Veterinary Society for Surgical Oncology and the Veterinary Interventional Radiology and Interventional Endoscopy Society. He is the author of textbook chapters and numerous scientific articles and has been recognized for lecturing nationally and internationally.

Through minimally invasive (or keyhole) surgery, Dr. Thomson is driven to minimize the pain and complications related to surgery while maximizing patient outcomes. Similarly, with the use of interventional radiology (or moving x-rays), Dr. Thomson can treat various forms of unresectable or metastatic tumors (liver, prostate, nasal tumors, etc) through chemoembolization, provide palliative stenting for obstructions of the urinary system and blood vessels, and embolization for vascular anomalies such as liver portosystemic shunts.

Dr. Thomson is also an active participant in clinical research with Ethos Discovery, with projects focusing on minimally invasive treatments for osteosarcoma, thrombocytopenia, urogenital cancer, and several others.
