I love how caring the staff is towards my pup. She is an anxious girl when she comes in yet they love on her and make her feel comfortable. I won’t take her anywhere else. Just chilling waiting for them to come in and come back in.

My family has been bringing our pets to Hillside Animal Hospital for years. The staff recognize us and our pets, they are wonderfully caring and accommodating to our nervous dogs. This is the best veterinary service our family has recieved in a life time of owning pets.

I have had the best experiences at Hillside Animal Hospital. Dr. Aaron Willis is very patient, thorough, and thoughtful. They put up with us anxious, first-time dog moms very well. The whole staff at Hillside is passionate and honest. You just get the feeling that this hospital and its employees genuinely care about animals and the community.
