After finishing the School of Applied Art in Zurich, Tissi joined a design consultancy, but this job didn’t offer much of a creative challenge. She started looking around for a new place and that is how she met Sigi Odermatt, who was known for his bold style and rebellious attitude towards industry rules. He had his own studio and hired Tissi as an apprentice. After a decade, she became a partner and the studio was renamed to O&T.
