Dana is the best, but I've never had a problem with any of the other piercers either! They're always very helpful and professional and make sure you really know what you're getting into, and they will help you pick placement and jewelry. I've had my monroe fixed after getting it messed up at another place (which sold me and I never went anywhere else) my septum 2x, and I'm heading back after Christmas for my philtrum and septum (again. hopefully.)
They're more expensive than going to the Piercing Pagoda, but you're paying for much higher quality piercing and jewelry. Definitely worth the money.
