It's important with any animal to find a qualified vet you trust and can build a relationship with before an emergency if possible. Talk to other people with reptiles, herp societies, rescues, ask for recommendations. Not all vets are created equal, some will treat animals they know nothing about, some are working with knowledge from 30 years ago, some have their own reptiles and keep up with current practices. I live in a pretty rural area and after about a dozen phone calls was able to find several vets I would trust with a reptile within a 5-6 hour drive but it took some effort on my part. Also keep your hopes realistic, if a reptile needs a vet, it's often a serious issue that may not be curable or has a poor recovery rate. The reptile vets I have visited have been reasonably priced but when you get into surgeries it can get expensive fast, like any pet. There's only minor health issues you would be able to deal with at home.
