  • "Took my 3 y/o tortoise recently and I was pleasantly surprised. Not only was the vet knowledgeable and kind, but the overall visit (including an x-ray) was reasonably priced. I definitely recommend and I will be returning for future services"

    Diane J.
  • "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!"
