Dr. Hahn, DVM
I grew up 12 miles south of Pittsburgh, received my BS at Penn State University as an Animal Bioscience major and then started graduate school in Pittsburgh at Duquesne University. I got my start in vet school at the University of Liverpool in England and then transferred to the University of Tennessee where I received my DVM in 1998.
I met my wife, Julie, at the University of Tennessee Veterinary School and we graduated together. We have 3 children (Anna,Addie, and Ben) with 2 in college and 1 in high school. We have a small farm in Meadowview, VA and have taken in all kinds of animals over the years, but my favorite is my 12 year old lab, Maggie.
I started my veterinary career in Abingdon where I worked for 10 years, then took a position as an Emergency Vet at the Airport Pet Emergency Clinic. After 12 years of emergency work a new door has opened and I have decided to assist several hospitals in the area as a Relief Veterinarian. So glad to be part of the team at Kingsport Veterinary Hospital.
