Some of the previous posts have hinted at it already, but I am a stickler for safe piercings. The company was founded on it. So, I am a big supporter for the Association of Professional Piercers. In fact, someday in the near future I would like Pierced Edge to be a corporate sponsor. One way they cater to the piercing community is they have a Conference/Exposition solely for the piercing industry.
If you are in any way associated with the piercing industry and if time and circumstances allow, you should attend it. This year it will be held June 9-14 in Las Vegas. There is going to be a huge amount of information being shared here. Even if you thought about becoming a piercer, it is highly recommended you attend as they have classes that are set up for beginners.
