The staff at Callahan Drive Animal Hospital is committed to maintaining a high level of customer care. In a world of automated messages and self check outs, we value face to face communication and a relaxed, friendly environment. Our staff is like a family here, and we want you to be part of our family.

Dr. James Hilla

I spent my youth in Clifton, New Jersey and graduated from Montclair State University in 1989. After graduation I applied to many veterinary colleges and chose the University of Tennessee in Knoxville. My passion has always been exotic animals which is why I focused on UT and its exotic program.


Gwen Graning

Born and raised in Knoxville, I have worked for Veterinarians from the time I was 15 years old. Before graduating from LMU, I was working at the U.T. College of Veterinary Medicine in the Department of Environmental Practice (exotic medicine). Formerly a licensed tech, now my focus as hospital manager is to treat team members and clients the way we always wanted.


Samantha Thorndike Stark

My name is Samantha and I am the office manager at CDAH. I started here in April 2011 as a vet tech but took over the front when our receptionist took a break for maternity leave. I have a B.S. in Animal Science from the University of Massachusetts Amherst. I have 2 cats of my own, Loki and Grim. They are absolute trouble makers and I am so lucky to have them. I never had a dog growing up due to allergies, but now I have a hundred dogs who I get to spend all day with. We aren't kidding when we say we love your pets like you love your pets.

  • "Doc Villa ALWAYS takes care of Studly Dudley!! I will ALWAYS recommend Callahan Drive Animal Hospital & their entire team as they truly do care for your animal in the same way you do!! Dr Villa has cared for Dudley for most of his SIXTEEN years & he’s still happy, healthy & strong!! I strongly believe, Stud has made it to this old age so gracefully due to the care he’s been given with this facility!! I would not trust another team than Callahan Animal with my “first child”, the only place for us to go!! Highly recommended!!"
    Lauren H.
  • "10/10 experience was even better than hoped for. As a snake owner, you hear things about vets that make you question taking them and it was very comforting and nice to have someone who not only helped but took the time to talk about caring for them properly. Thank you guys so much!"
