I was born in 1977 in Poznan, Poland. In 1992 I started studying violin-making in Music High School in Poznań under the leadership of my father Antoni Krupa. In 2002 I graduated the violin-making faculty on Music Academy in Poznan. Since 2001 to 2002 I had training bow-making at Gregor Walbrodt’s workshop in Berlin.
