Dr. Shelley Mathis, DVM
Dr. Shelley Mathis spent her youth as an air force daughter traveling the US though eventually calling eastern Washington home. She completed both her undergraduate degree in nursing and veterinary degree (1988) from Washington State University. She holds the honor of being the first WSU veterinary student to give birth to children and not drop out of school: a daughter in her sophomore year & a son in her senior year. Dr. Mathis began her clinical work in western Washington eventually starting a practice along with her husband who is also a veterinarian. After 10 years of practicing in the States, they moved to Nepal (envision Mt. Everest) with their children and their cat, where they taught veterinary medicine in the remotes of the Himalayas. About 6 years later they sojourned north into China and took up residency on the Tibetan plateau again teaching veterinary medicine in rural areas and at a government agricultural school. Their time in Asia was filled with adventure, and a vast variety of animals and people who blessed their lives.
Returning to the United States, Dr. Mathis entered back into clinical medicine and eventually transitioned to Medford Animal Hospital in 2015. Dr. Mathis considers it a privilege to work with clients and their beloved animals, establishing and promoting optimal health and wellbeing. In her spare time, Dr. Mathis enjoys all things outdoors, especially if it includes family. She also continues to volunteer overseas, is involved in her church, and spends time loving on her grandchildren.
Through the years she and her family have had almost every kind of animal you could possibly domesticate; she presently lives with one epileptic cat rescued from China, another cat locally rescued and her husband (of 37 years) rescued from veterinary college.
