Following numerous podiums in Switzerland during his teenage years, his entourage pushed him to compete with the cream of the crop of European skaters at the age of 17.
One year later, Greg won 2nd place at the Red Bull Bowl Rippers Amateur in Marseille, one of the legendary competitions in the discipline, which allowed him to
compete the next day with the pros. A dream come true, Greg was challenging his American idols.
Known for his long "frontside grind" and surfing style, Greg was quickly spotted by Swiss Skateboard in 2018. In fact, the Swiss Skateboard Federation quickly set out to form a national team for the Olympics.
