The doctors and staff are very professional and personal at the same time they are very careing about you and the pets. The office is very clean and friendly.

The pricees are comparable to other vet clinics.

I would definitely recommend to other people.

Excellent service every time. Friendly staff.... and pets are treated as royalty! Our cat Maxie has a LOUD voice to announce his arrival, but once Dr Gandolphi put his gentle hands on our cat, this black velvet feline settled down and enjoyed the visit. Thanks DR G for your excellent care.

COMPANION ANIMAL HOSPITAL is the BEST... for all types of animals. The staff keeps things moving and has the paper work ready as you leave. This is a 5-STAR Vet service.

Awesome care for Bubbles. The spaying procedure went really well. She is doing much better today and is already playing around with my children this morning (less than 24 hrs after the procedure)!

I have gone to the same Vet for over 30 years. When my cat needed an urgent appointment they were unable to help, which I was very disappointed. Checking online I called Castro Valley Companion and was able to get an appointment right away. Once I was there, the Staff was so kind ad helpful to my cat. I could not be happier with the excellent service and care. I highly recommend this Vet for excellent care and service to our fur family members.
