Dr. Greg Thompson

Dr. Greg Thompson comes to us from South Bend, Indiana.  He graduated college from Purdue University with a degree in Animal Science and Biology and went to Veterinary School at the University of Wisconsin. His first year after graduating with his DVM was spent focused on equine medicine as an intern at Pilchuck Veterinary Hospital in Snohomish, Washington; horses are a primary area of interest for him.  While there, he rotated through equine surgery, medicine, and ambulatory. Among his duties as an intern, Dr. Thompson routinely assisted with middle-of-the-night colic surgeries, performed lameness workups and joint injections, and managed and sutured wounds.  Upon completion of his internship he moved to Brookings, Oregon when he practiced as a mixed animal veterinarian.  After a year on the Pacific coast, he moved back to the Midwest to practice closer to home.  After a year of continued mix animal practice, Dr. Thompson decided to focus mainly on horses and small ruminants.  When it comes to practicing medicine on horses, some of Dr. Thompson’s passions are equine dentistry, lameness, and reproduction. Outside of work, Dr. Thompson enjoys horseback riding and playing golf.
