  • Mike Copenhaver, DVM

    Veterinarian/ Managing Veterinarian /Owner 

    Dr. Mike Copenhaver received his Doctorate in Veterinary Medicine from Michigan State University in 1995.   He started his veterinary medicine career working in practices in rural Kentucky and SE Virginia, and soon after, started his own veterinary practice in southern Ohio.   It was a very successful practice, but both Dr. Copenhaver, and his wife Darcey, were drawn to the beautiful mountains and lakes of East Tennessee.  They relocated to Dandridge and Dr. Copenhaver joined Appalachian Veterinary Hospital in 1999 as an Associate and co-owner.  In 2005 he became solo owner of the practice.  Since taking over, he’s turned the practice into a full-service hospital which includes a digital x-ray, an advanced in-house diagnostic lab and laser surgery and therapy center.  Dr. Copenhaver has always been driven by the desire to provide advanced veterinary services to the community.  In addition, he has a passion for surgery and routinely does surgical procedures, such as orthopedics and bone plating.   

    Dr. Copenhaver has been happily married for 22 years, to his wife Darcey. She also happens to be the hospital manager at Appalachian. Together, they have 2 rescued Chihuahua mixes, Poco and Pedro, who also come to work with them daily to help “manage” the place.  I guess you can say it’s a bit of a family business!  During his free time, Dr. Copenhaver enjoys riding his BMW GS adventure motorcycle, traveling and reading.
