Be sure the doctor is a board certified plastic surgeon, not a board certified cosmetic because there isn't a legitimate board for cosmetic surgery, and such doctors often never completed plastic surgery residencies (or, like Dr. Johnson, failed their board certification) or any surgical residency at all.
Also unreliable are city magazines that feature the "best" doctors. The worst doctors often get listed because they have press agents.
Look for someone with privileges at the biggest burn treatment centers in the state because the best plastic surgeons do a great deal of reconstructive surgery.
