Langley animal clinic is where I go. They have I think 2 doctors that are able to work with small animals and rodents who work at the clinic, and they won't let you make an appointment unless there is a small animal vet on-duty.

They do treat large animals as well, though, they aren't an exotics vet specifically.
It's pretty reasonable too, $40 for a visit, and then extra costs for medications that the pig may need. I was expecting more when I went.
