Karen J. G. Joines, DVM

Dr. Karen

Dr. Karen J. G. Joines joined the TVC team as a veterinarian in July 2023. She is originally from western North Carolina and from a young age she knew God was calling her to work with animals. Dr. Joines, or as we call her Dr. Karen, has a passion for practicing both companion and large animal medicine.  Dr. Karen’s love for animals has come honest having had a wide variety of pets including rabbits, dogs, cows, and even some fish along the way. One day Dr. Karen dreams of owning a pair of ducks named Aflac and Ferdinand. Each one of her pets has impacted her life and taught lessons that she carries into every appointment.

Dr. Karen recognizes that the bond between animal and human, regardless of your furry friend’s size, is valuable and she strongly believes in forming lifelong relationships with all her patients and clients.  Pet parent education and empowerment are a goal Dr. Karen strives to achieve with every case she has the honor to take part in.

Dr. Karen is a club leader for a local 4-H program in Carroll County and is also involved at the church where she and her family attend. When relaxing she can be found working on her farm, exploring a new place that takes her outside on a hike, hand quilting, or making silk flower arrangements. Dr. Karen loves spending time with her family and friends, enjoys bluegrass music, the outdoors, and everything to do with the mountains of North Carolina.

Dr. Karen is excited to be back at TVC as a veterinarian! Many may remember her from when she worked at TVC before vet school as an assistant, or even before that when interning her senior year of high school back in 2010, and for a short time as a technician waiting for her license to be finalized after graduating veterinary school. Dr. Karen graduated with her undergraduate from Bridgewater College before obtaining her DVM from Ross University.
