There are only a couple of places where I'd trust myself (or recommend others) to get pierced at and this is one of them places.
Resident pierce master Aidil has had more than a decade of piercing experience and every paying customer that's been pierced by him is a happy one.
The most important thing about piercing is to make sure that you get someone who knows how to keep things sterile and pierce in a way that'll minimize the risk of infection.
I'm a believer that piercing shouldn't be done with earring guns but with a sterile needle. They last longer and heal better. Don't forget to ask about and practice good aftercare!
