In 2005 Ms. Breiner made her choreographic debut in the prestigious "Young Choreographers" evening of the Stuttgart-based Noverre Society, and her work thereafter quickly gained acclaim. In 2007 she took on a daunting creative challenge in the choreography of Zeitsprünge, an evening that merged dance and art in the exhibition spaces of the Kunstmuseum Stuttgart, created for students of the John Cranko School. The piece highlighted the works of Willi Baumeister and gained great critical acclaim. She has since created works for the Stuttgart Ballet, Latvian National Ballet, Kevin O´Day-Ballet Mannheim, Ballet Augsburg, and the Salzburg State Theatre.
In 2011 Ms. Breiner was invited to choreograph and direct Großstadt-Triptychon, a collaboration between the opera and dance companies of the Musiktheater im Revier Gelsenkirchen. One year later she was appointed artistic director of that theater’s newly formed ballet company Ballett im Revier, a company of 14 international dancers. Her first full-length story ballet for the company—Soot, a retelling of the Cinderella tale (Ruß - Eine Geschichte von Aschenputtel)— received Germany's most prestigious theatre award "Der FAUST” for "Best Choreography" in 2013. She followed this success with new choreography for On the Town, Swan Lake, and The Tragedies of Othello. Another dance-opera collaboration, Charlotte Salomon: Death and the Painter (Der Tod und die Malerin) with commissioned score by composer Michelle DiBucci, received wide critical acclaim and again brought her the “FAUST” award in 2015.
In 2016 Ms. Breiner was invited to the Ruhrfestspiele Recklinghausen, one of Europe's oldest theatre festivals. Her creation there—Prospero’s Island (Prosperos Insel)—a retelling of Shakespeare’s The Tempest, was immediately taken into the company's repertoire. This year, 2017, she is creating her first full-length symphonic ballet, The Vital Unrest, including Camille Saint-Saëns’ Third Symphony and a new commissioned work by Latvian composer Georgs Pelecis.
