The doc who did my skin punch biopsy was a specialist in the Neurology Department of The Cleveland Clinic, which is local to me. She was the only doc who did them, but I don't think she was a dermatologist. If you want, I can find out what sort of specialist she is so that at least you'll know.

My aftercare also involved keeping a band-aid on each of the three sites for
X amount of days - can't remember, but changing them each day. The sites were definitely smaller than a dime. Can't even see where they were anymore.
