The facility is fantastic and the vets are top notch. This is easily the best vet center in the east bay. There are a lot of vets, including a number of specialists, and the equipment is state of the art. I had a dog at another vet that casually said that he might have a very serious condition. I took him to Bishop Ranch where they brought a specialist down from Davis to spend a long time going over my dog. In the end, he was fine and the first vet was wrong. It happens, but it was very expensive to check up on and if the first vet hadnt been so convinced of his (non-existent) condition, we wouldnt have pushed so hard to get him checked out like this. It was worth it, but still.
If any other vet had told me that the first vet was wrong, I wouldnt have been 100% confident, but I trust the vets here more than I trust most MDs. Its not cheap, but for the best care and peace of mind, this is the only place to bring your pet.
Disclaimer: I have been friends with two of the owners for many years, one all the way back to when we were in college together. Nevertheless, I think this is a pretty objective opinion. If anything, because Ive known them so long, I can attest to their trustworthiness.
