Gothamist posted an interview this morning with Dr. Zizmor, the subway dermatologist. I've been in New York about 10 years, and Dr. Zizmor's ads were among the first I noticed when I moved here and became a regular subway commuter. I've always had a low opinion of Dr. Z's practice. I tend to devalue local businesses that I see advertising in the subway, mostly because the older cars are so dingy and the ads look weathered and of poor quality as a result. I think it reflects badly on the business that chooses to advertise down there. My ex-wife used to work for a dermatologist, and everyone assumed that he was Dr. Z. (He was not.) Maybe that's just my opinion. I've never asked anyone if they've patronized an establishment based on a subway ad.
Stigma or not, the ads work for Dr. Z. He's built a successful practice and was ranked as one of the 10 best doctors in America by Harper's. It's good to know he's a reputable physician, should I ever need to have a tattoo removed.
