Kerstin Dietl studied early music at the Hochschule für Künste in Bremen from 2011 to 2018. Initially Tanya Aspelmeier and Harry van der Kamp were her teachers, but she learned most of her studies from Gemma Bertagnolli and Peter Kooij . This intensive training was further refined by working closely with Dorothee Mields, Paul Agnew and Sophie Daneman, as well as by masterclasses with Gerd Türk and Emma Kirkby. She also receives important musical impulses through her regular coaching with Jörg Straube.

As a soloist, Kerstin has worked with renowned ensembles such as Musica Alta Ripa, Schirokko, the Arp Schnittger Ensemble, das Kleine Konzert, the Bremer Philharmoniker and the Deutsche Kammerphilharmonie Bremen. Although her focus is on baroque music, her repertoire also includes works from the classical and romantic periods. She is a sought after performer of oratorios by Handel and Bach and also an accomplished interpreter of english, french and italian baroque music. 
Since 2016 Kerstin has gained experience working internationally on the opera stage. As a participant of the Young Artist Gloger Academy under the direction of Olof Boman, she made her debut as Cupid in John Blow’s opera Venus and Adonis in Norway. This was followed by performances with Ketil Haugsand in Portugal. In 2017, Kerstin was selected to appear with the European Baroque Academy under the direction of Paul Agnew. Kerstin performed the title role of Dido in Henry Purcell’s Dido and Aeneas at renowned festivals in France, Slovenia, Spain and Switzerland. She also sang the roles of Belinda and second witch in France, Portugal, Belgium and Italy.

As an ensemble singer Kerstin is in demand throughout Europe and can be heard as a member of renowed ensembles such as the Rheinische Kantorei (Hermann Max), the Balthasar Neumann Chor (Thomas Hengelbrock), and Collegium Vocale Gent (Phillipe Herreweghe).
