Transcript for What undercover journalists discovered about man posing as a dermatologist
BRYAN BURROUGH: You've got two different journalists who both simultaneously are showing up at SkinOvations posing as patients, and asking him to do things that he should not do, that he does.
- I made an appointment to see Dean Faiello, and I went with an undercover photographer. He told me that he could remove a mole here and a mole here.
- Are you bothered by one over here or--
- This one?
- There is small right there.
- Would you take that off?
- If you want.
- He said that he could remove this with a laser, and he didn't say that he was going to do a biopsy. I might have had facial cancer, and he would not have diagnosed that.
- At the same time, The Post's, Jeane MacIntosh goes in for the same kind of treatment.
- He literally just took a look at it, didn't do a biopsy, didn't ask me my medical history, didn't ask if I'd ever had it checked before, or anything like that.
BARBARA NEVINS TAYLOR: I don't see any medical certificates. I don't see anything like that. I asked him if he was a doctor. Are you a doctor?
BARBARA NEVINS TAYLOR: I still wanted to make sure I heard it right. I asked again, so you're a doctor? So I can trust you.
BARBARA NEVINS TAYLOR: I don't have to worry. He even told me where he supposedly went to medical school.
- I went to University of Medicine and Dentistry in New Jersey.
- He built a whole persona of being a medical doctor. And people bought it hook, line, and sinker.
