Our caring veterinarians are experienced, skilled, and here to help.
Dr. Teresa Bessler
Dr. Bessler grew up in North Dakota and attended Northwest College and the University of Wyoming. While in college, she worked at a vet clinic and at the Wyoming State veterinary lab. She graduated from the Kansas State University School of Veterinary Medicine in 2001 and joined Buffalo Vet Clinic in 2006. Her veterinary interests include general practice, small animal medicine and dentistry. She believes the most satisfying about being a vet is the variety of work, learning new things, and figuring out a difficult case. She is a member of Wyoming Veterinary Medical Association.
Her husband, Gary, is a taxidermist, and they have two children, Colby and Cassidy. Dr. Bessler has dogs, cats, horses, and sheep, and her hobbies include raising lambs with her family, attending her kids' activities, and cross stitch. She is also a 4H leader.
Dr. Garry Gotfredson

Dr. Gotfredson grew up around livestock in Worland, WY, where helping the local veterinarian was a joy.

He and his wife Nicole, a certified veterinary technician, purchased Buffalo Veterinary Clinic from Dr. Kurt Walters in 2022. Dr. Gotfredson truly enjoys working in a mixed-animal rural practice because of the variety of patients, cases and conditions seen and treated every day. His special interests are small animal surgery (especially orthopedics) ultrasound, equine surgery and medicine, bovine medicine and surgery and herd health.
Dr. Gotfredson and his wife have four children, Levi, Lexi, Gray and Elise. They are joined by two French bull dogs, Charlie and Darla, a golden retriever named Hazel and two cats, Newt and Hero.
