So pleased with my cat's care by Dr. B and team. Happy to wait in car while Oliver was examined and brought back to my car more relaxed than when he left. Dr. B came out to discuss his meds and the whole experience was very friendly and professional. Thank you to all of you! My Guinea Pig (Speedee) had been going to Castro Valley Companion Animal Hospital for over 4 years and Dr. G, Nikki and the rest of the staff has been fabulous with him.

Very friendly staff. They were thorough with the exam and gave me peace of mind for my doggies injury (fox tail infection). Would recommend them.

Compassionate and friendly healthcare for our fur friend with phenomenal customer service and turnaround time to boot! Special shout-out to Edward and Stefan for making sure our Mocha was well taken care of quickly when needed in a pinch. Highly recommend this hospital for your pets veterinary care.

My two Pomeranians have been clients of Companion Animal for over 12 years. In that time the practice has grown from one to several vets and many techs. They have helped manage medical issues with my dogs from the minor to the severe and I wholeheartedly recommend CVCAH.

I had been going to Hills vet in CV for 19 years and suddenly things changed during covid and I was left with no more of the doctors we knew and no more of the same faces we knew. They entirely changed the staff. This new thought of having to find a new vet was a scary thought. My dog and cat are my kids too! They needed the best care possible. I searched Facebook groups, nextdoor recommendations and asked many neighbors and friends where they go for their vet.

Many people kept saying Companion so I nervously called and got some info. From the first call with Lorenza I was at ease. She was fabulous and answered all my questions. She was able to get us in the same week, total luck I think! When we arrived they immediately came out to the car and checked us in. Anjela was great and took us in and got info and weights.

My dog is scared to death of the vet and after a few minutes she had him laying down on the table calmly! We waited no more then 1 minute from being checked in with Anjela until the doctor came in the room. The doctor spent a long time with both of my animals. Dr. Harper very detailed in every conversation topic and explained things clearly. The procedures my pets had done were also very reasonable. What an amazing team you have. I am thrilled this is our new vet for many many years to come! Thank you, Thank you, Thank you!

There is no other vet that I can think of that would be so accommodating and helpful. I am so relieved and happy to have found companion. I am having some issues with my puppy and I had her evaluated and treated by Dr Harper. I was having a few concerns about her treatment and medication and Dr Harper called me within a few hours to discuss all of my concerns thoroughly and put me at ease.

She even had a partner veterinarian email me an article on the health issue that my puppy is suffering from. Honestly above and beyond. The staff couldn't be more warm and loving to the animals in their care. I am so grateful to have found this vet! After a very mediocre visit at Castro valley animal hospital that left me feeling like it was a get rich quick scheme or a bait and switch type of thing, I'm so happy to have a polar opposite experience at companion.

The first place wanted me to prepay for all of my puppies treatment and I was inclined to keep going because I'd already paid for some of the treatment. I just couldn't bring myself to go back. Anyhow, thanks so much for putting me at ease, and for caring for Rosie so well.

Dr B is compassionate and really cares for the well being of my 2 Shih Tzus. Just wish that there was a more holistic approach towards their overall health. Friendly and caring staff and clean organized clinic.

All the vets and technicians and other staff very knowledgeable and friendly. They work with a variety of pets: dogs, cats, birds, small animals. I have found them to be more reasonably priced than other vets. Easy to get appointment. Very caring and compassionate. Really listen to the pet parent. They still have Dr. Gandolfi with them, who works with traditional and alternative treatments.

I've been using this vet for several years. They became my preferred vet after another well-known vet nearly killed my cat. This vet saved his life! There's even free coffee and a Clean bathroom! They do not smell like so many vets do.smells clean - not deodorized covering urine smells.

I would NEVER consider another vet. Dr. B is one of a kind. She's the best vet we've ever worked with and we love her. She saved our dog's life and continues to be there for us always. Thank you to everyone at Companion. You guys are the BEST!

Dr. Bercovitz has been both of my pet's veterinarian. our dog, Murphy, for 14 years and our puppy, Lucy. Dr. B is the most gentle vet and I trust her completely. Because of Dr. B our Murphy had a very long and good life. Even with health issues as he got older, she helped him be as comfortable as possible. I know she will give Lucy the same care and the staff at CVCAH is extremely nice, caring, and their technicians very knowledgeable. Dr. Gandolfi is wonderful too!
