Friday began working with clients for post-operative scar coverage when she met Stacey Watson, a breast cancer survivor, for her first tattoo in 2009. The resulting seashells on this Southern California mermaid crested the leading edge of a genre-breaking trend and created a movement of reclamation. The non-profit charity Personal Ink (P-Ink.org), of which Friday is a board member, pairs survivors with some of the most talented tattoo artists in the world for masterful post-operative scar coverage.

In 2010 Friday was approached by Dr. Oren Z. Lerman of Lenox Hill Hospital's prestigious Department of Plastic and Reconstructive Surgery about performing nipple tromp l'oeil tattooing and repigmentation. Since then, Friday has fully embraced her role as a medical tattoo artist and has assisted Manhattan's top surgeons in completing miraculous breast reconstructions on survivors from around the world.
