As a small child, Maria would rummage through her mother's jewelry box, wearing all of her necklaces at once stringing them around her neck and torso. She continued her love for jewelry as she grew, sketching designs, stamping brass bracelets and eventually purchasing her own piercing gun and practicing on herself and friends.Experimenting was a huge part of her beginnings, with ads in the back of the New York Press, she would have clients come to her apartment to get piercings. In 1993, with a small amount of money from her father when he passed, Maria took the opportunity to open her first store in East Village, New York.

Maria Tash went international in 2016 opening her first international store in London. She now has locations in Rome, Dublin, London and Dubai. Rihanna, Blake Lively and Jennifer Lawrence are a few of Maria Tash's celebrity cult followers. Maria Tash originally specialized in naval jewelry and expanded into body piercings and jewelry as her business grew. Her innovations include Forward Facing piercing, threaded studs, invisible set diamonds on her studs, clicker rings and True-fit navel curves. A piercing course by Fakir Musafar in San Francisco gave Maria Tash inspiration for innovative piercing.
