Your description of the interactions you’ve had with this vet remind me of a similar experience I had with a vet practice in Colorado. I was seduced by the shiny new building! But I just felt like the vet didn’t have my cats’ best interest in mind (she had to pay for the shiny new building) so I switched to another vet (in an older, kinda shabby but immaculately clean buildingMy kids go to the vet regularly, are always up on their shots and preventatives, I spend a small fortune buying them what I think is best food that I can, I feel like I'm a diligent owner but without fail, I leave each appointment feeling like garbage about something.

My current vet knows I feed raw. He has a copy of the recipe I use. And while he may not be enthusiastic about it, he’s respectful of my choice and approves of the recipe. He also works with me to save me money. He found a much cheaper source for the insulin I was buying for Max and saved me hundreds of dollars.
You want someone with expertise, of course, but someone who discusses, listens, respects. I’m glad you’re looking for a new vet!
