David Gasser was born in 1981 in Brixen in the South Tyrolean Eisack Valley. For his training, the Villandro native finally moved to Lasa in Val Venosta, where he attended the three-year full-time school for stonemasons and stone sculptors from 1995 to 1998, learning to work primarily with Covelano and Lasa marble, probably the purest marble in Europe.
After completing his training, he initially gained valuable professional experience at the Höllrigl stonemasonry company in Lana. As the youngest participant among the stonemasons, he competed in the South Tyrolean team at the 35th World Professional Championships in Montreal and achieved 5th place.
During his military service from 2000 to 2001, David Gasser worked as a lorry driver before setting off on a three-month trip through Australia in 2002.
