    Brandy B
  • "Erica Mckinney is the best vet ever! I've been going to El Paso since 1992 and was seen by Dr Herod and Dr Oehmke, but when she joined the clinic, it was AWESOME. She helped give life back into my cat Tigger for years until his sickness caught up with him, and she helped me through that difficult time. She is very loving towards all of my pets. She is very thorough with what she is going to do and also lets you know how much it will cost before anything is done."
  • "El Paso Animal Hospital and it's staff, especially Dr. Jeff, have always been the nicest people to my pets and me. He has saved my cat's and my dog's lives and I thank them soo much for that. They will definitely make you feel comfortable leaving your pets there!"
  • "When Dr. Gary kissed my sick rats head, I knew I had found a loving, caring vet clinic. I take all 3 of my dogs and my 3 cats to them for excellent care. They are less expensive than other vets I have found while still providing excellent pet care."
