Complimentary exams

We offer complimentary exams for first time clients. The complimentary exam is valid only with vaccines. If your animal is running a temperature during the exam we will be unable to vaccinate.

If you are new to the area or just looking for a new vet but don't need any vaccines or services for your pets, we offer a complimentary meet and greet for new clients to tour the hospital and meet the staff.

  • "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!"
