My answer is simple - I would NEVER have a dermatologist do a tummy tuck on a friend, family member or anyone for that matter. A dermatologist is not trained to do surgery more complicated than that involving the skin.A tummy tuck is major surgery. The longer a surgeon trains at his craft, the finer his skills and the better his judgment become. Board certification in Plastic Surgery (see below) is a bare minimum. Board certification in an additional surgical field recognized by the American Board of Medical Specialties, or for that matter “triple-board certified,” attests to a doctor’s advanced training and skill and judgment. It also means that they have attained Chief Resident Status in more than one field during their training which means they essentially ran a large departmental service and had senior decision-making and independent operating responsibilities. It is this step that is most maturing for a surgeon.The institution where the surgeon trained is also important. More renowned schools usually attract the best faculty.You can use the internet to research the background of a prospective plastic surgeon quickly. Please do this prior to making an appointment. “Just because you wear a baseball cap it doesn’t mean you are a good ball player.” The same applies to anyone wearing a white coat—it doesn’t make you a plastic surgeon, much less a great one.Caveat Emptor in Latin means “Buyer Beware.” In most states, including California, any physician with a medical school diploma and state license is viewed as a doctor and a surgeon—even without any formal surgical training. In some cases even doctors who have completed only the minimal requirements (medical school, licensing examination, and a one-year internship that need not include surgical training) are touting themselves as “cosmetic surgical experts.” They make these claims of expertise despite the fact that they are only formally trained as family practitioners, OB/Gyns, emergency physicians, dermatologists, or ear-nose-throat specialists. Even physician assistants and nurses have made such claims. See the below link on how I would choose a plastic surgeon.
