The Association of Professional Piercers is the oldest and longest running organization for professional piercing. It was founded in the USA by Michaela Grey and colleagues. The first members were professional piercers from the Gauntlet and other early piercing studios. Today there are APP Members all over the world. Not all piercing studios have joined this organization, but it does not mean that the piercing studio is not professional. The organization works to disseminate information to both customers and piercers, and they work with legal assistance to countries where the piercing is a bit beside the law. The organization also produces annual meetings that bring many of the best piercers in the world together to share knowledge.
