Yeah he's not perfect, but there are not a lot of options for exotic vets in my area. The closest snake vet who is an expert is at least 300 miles away. I'm glad I checked it out and know what to expect.
The local pool of information on exotics in my area is very poor and mostly propagated by a local petstore chain that keeps ball pythons and boa constrictors together. They have also kept rosy boas in Kritter Keepers with no heat source, no hides, and only enough room for the snake to be balled up and a deli cup of water. Really terrible conditions and nearly all of those snakes had bad attitudes.
Considering several of the questions he asked me about her environment and what he recommend, it seemed pretty in sync with what is talked about on this forum. I found that to be a really good sign. I also used to do a lot of work for an exotic animal rescue so I have experience working with vets. There is almost always a learning curve, but most vets really care about the health of the animal and are eager to learn new things. With more exposure to exotics they get better at doing their job.
Long story short, definitely always be mindful, but I'm not going to sweat it too much. Daisy's a healthy girl and has a medical baseline for the future.
