I'm a transgender male who's wanted my nipples done for a long time. Being post-op with chest surgery, I was having a hard time finding a shop that would pierce my nipples due to the fact that they were trimmed and grafted back on. I went to five or six shops prior only to be turned away.
Upon booking my sister for her first tattoo with Madison, I met Kenny, the piercer there. Not only was he super knowledgeable but he was also really respectful towards my trans identity. He was confident in his abilities, took a look at my chest and what he'd be working with, and said he could totally do it. It's been a few months and they've healed up beautifully with absolutely no issues.
I recommend this shop and it's artists to everyone I chat with about body mods now. I'll definitely be coming back.
