Marie Hermo Jensen started dancing at her Mother´s dance school, Hammerfest Ballettverksted in Hammerfest, Norway, where she was born and raised. The professional contemporary dance company, which developed alongside the school changed name a few times through the years, but is today called Stellaris DansTeater and is the oldest independent dance company in Norway today. The company is owned by Artistic Director and Dance Artist Solveig Leinan-Hermo, and is likely the northernmost of it's kind.

She returned home.
