Born in Budapest, Hungary, László began dancing ballet at 6 years of age.  By the age of 10 he was accepted into the Hungarian National Ballet Academy and pursued a career as a ballet dancer (Vaganova).  Throughout his years at the Academy he performed in numerous classical ballets at the Hungarian National Opera house including the Nutcracracker, Sleeping Beauty, Spartacus, and many more.  When he was 19 years old he took a job offer in Vienna, Austria, in the musical Cabaret.  This began László's professional career as a musical performer.

For almost a decade he performed in many prestigious theatres throughout Europe with musicals such as Jesus Christ Superstar, Joseph and the Amazing Technicolour Dreamcoat, Cats, Miss Saigon, Evita, and Fame. During his musical career he was exposed to and became interested in many forms of dance and in 2005, László opened his own dance school, FAME Dance Studio, and began teaching hip hop back home in Hungary.  Within five years the school expanded to four different locations  with his students competing in international competitions.  In May 2010, just before moving to Canada, László's students achieved first place at the International Dance Federation World Championship with their junior hip hop team.
