He is currently coached by Prof. Susanne Schimmack.

Since the beginning of the 2021/22 season, the tenor has been a resident guest at Oper Graz, where he will make his role debut in three premieres: in the leading roles of Juan Damigo in N.

In the 2019-20 season, Mr Koziorowski made his role debut as Grigory/Dimitri in the new production of "Boris Godunov" at the Mainz State Theatre to great acclaim, and appeared as Vasco da Gama in "L'Africaine" at the Theater Lübeck.

While still a student, he was hired in 2012 for two years as a member of the young ensemble at the Musiktheater im Revier Gelsenkirchen. In the summer of 2013, Mr Koziorowski was also the first-prize winner at the Kammeroper Schloss Rheinsberg; at the opera festival there he sang the four Servant roles in “Tales of Hoffmann. As a result, he performed several times and regularly at Theater Kiel until autumn 2015, including as Fatty (Rise and Fall of the City of Mahagonny), Merkur (Orpheus in the Underworld) and Hans Scholl (The White Rose). Other guest engagements during this time took him to theaters in Bremen, Dortmund, Chemnitz and Hagen.

Throughout his studies, he also cultivated a particularly close relationship to the Aalto-Musiktheater Essen. There Mr Koziorowski took the stage as a soloist in numerous children's operas, singing for instance Tamino in a "Children's Magic Flute", the Prince in "Sleeping Beauty" and the Witch in an adapted version of Humperdinck's "Hansel and Gretel". In addition, he played Ladas in "The Greek Passion" there and also worked in administration, as a theatre pedagogue and as head of the extras.

Mr Koziorowski also works as a concert singer. He has already sung the tenor solo in Beethoven’s 9th Symphony multiple times, most recently with the Bochumer Symphoniker under Steven Sloane. In addition, he has previously sung the Swan in Carmina Burana, Mozart’s Requiem, Haydn’s Creation, Verdi’s Requiem, Mendelssohn’s Hymn of Praise and Mahler’s Lied von der Erde. His concert activities have led him until now to the Konzerthaus Dortmund, the Philharmonie Essen, the Philharmonie Köln, the Berlin Cathedral, the Düsseldorf Tonhalle and the Elbphilharmonie.
