Unlike a podiatrist, a dermatologist went to medical school. If they're young, there's actually a good chance that they were among the very best medical students -- in the past few years, dermatology has become one of the more competitive fields in medicine because of the lifestyle (short predictable hours, high pay, minimal insurance hassles).

There are daft people in every field, but I would be delighted to have most of the derm residents and attendings I've met in an emergency (in fairness, I should note that this is a small sample, drawn from a couple top-tier hospitals, and biased towards people who do volunteer backcountry search and rescue).
