I am a trombonist and passionate musician based in Winterthur, Switzerland

As a trained classical trombonist, I am employed by the Swiss symphony orchestra Musikkollegium Winterthur.
With my ensemble SEBASS (Balkan & Romani music)

I've been giving concerts for 16 years and we have produced four albums.

Being a musicican is my passion and I love to create art with so many inspiring artists from around the world.
