  • "The Best Place for your pet. I have been taking our pets there for 25 years. They are the BEST! All of the doctors there are wonderfully caring and knowledgeable."
    Diane KH Derby, KS
  • "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."
  • "Great place to take your pets... The vets here have always been gentle and caring. I have used them for about 4 yrs now and do not have one complaint. I would recommend them to anyone who loves their pets!"
    Brandy B
  • "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."
