The THEATER HEUTE journal crowned Mondtag 2016's »young director of the year«, as well as »set and costume designer of the year«. His production of Olga Bach’s Die Vernichtung at Konzert Theater Bern garnered Mondtag his second Theatertreffen invitation in a row. In 2017 THEATER HEUTE named him »costume designer of the year«; the DEUTSCHE BÜHNE magazine chose him as »set designer of the year«. For his production Das Internat at Schauspiel Dortmund, Mondtag received another invitation to the Theatertreffen in 2019 - totalling three invitations to the prestigious festival within just four years. Furthermore, Mondtag also received the 3sat-Award for Das Internat in 2019.
