Product liability lawyers aren't as common as personal injury lawyers, but you shouldn't have any problem compiling a nice list of potential candidates if you need one. That being the case, be sure you research each one carefully before they even go on the short list: you'll need to find the ones with the most experience, best educations, and best track records.
Product liability law is a lucrative field, so it's attracted its share of shady lawyers. If you're ever concerned about a lawyer's qualifications, check to be sure they're a member of the state bar association; if not, don't hire them.
