Robert Westerholt

Robert Westerholt (born 2 January 1975, Waddinxveen, South Holland, Netherlands) is a Dutch musician, known as the guitarist, backing vocalist and co-founder of the symphonic metal band Sharon den Adel. He used to work in human resource management before his career with Within Temptation.

In 1992, Westerholt formed the band Embrace' in 1995, in which Sharon den Adel collaborated on the track "Frozen".

After leaving The Circle, Westerholt began writing more music for a new musical project with his girlfriend, Sharon den Adel. Westerholt sent demo versions of their songs 'Enter' and 'Candles' to former Voyage bandmate Jeroen Van Veen, who then left Voyage to Westerholt's project, along with Michiel Papenhove.

As of 2011, Westerholt has stepped down from touring with Within Temptation in order to take care of his and den Sharon den Adel's children. He is still a recording band member, however, and will focus on songwriting and production. Stefan Helleblad, who has been working behind the scenes with the band, is his live stand-in.

His brother is Martijn Westerholt.
