See what our clients have to say:

I have been going to Union Hill for over ten years. I could never have children so you must understand that all my pets are my "children." I have brought many of my "Children" there and I trust them with all my heart. I normally do not write reviews, but there are so many businesses that try to upsell you on your love for your pet. But Dr. Castle and Dr. Smith have always been honest to me. Sometimes the news is not what my heart wants to hear, but they care for their quality of life.

Have never had an unpleasant experience at Union Hill Animal Hospital❤❤ All employees are professional, compassionate, helpful and extremely nice. Dr. Castle and Dr. Smith are very experienced and never stop learning new things❤❤ I would not trust my wonderful animals with any other Veterinarian.

I have always had the best experience bringing my dogs here. All of the staff is professional and friendly. They care about the health of their patients! They use the latest techniques to provide top-notch care. I’m so glad I found this vet practice!

Cindy H.

I am so happy that I found this place. Both Dr. Castle and Dr. Smith are wonderful! In fact, the whole team has been really good to me and my dog. No matter what is going on with my pet, I never feel taken advantage of like I did at so many other vet hospitals. I feel like they genuinely care about me and my animals because they only recommend procedures and medications that are Actually necessary. I highly recommend Union Hill Animal Hospital.

Recently started bringing my 2 dogs here because of moving to this side of town. I really wish I had known about them sooner.. I was driving further & the service I was receiving was no way as friendly & personalized! We have peace of mind now that we have Dr. Smith & the entire staff. They really take the time to listen to your concerns & you never feel rushed! They're great people!
