Faber graduated 1987 from the Danish highschool in Flensburg, having achieved his Abitur.
In May 2010, the Südschleswigsche Wählerverband nominated him as a candidate for the mayoral election of Flensburg on October 31, 2010.
In the first round of election he was second to Elfi Heesch (CDU[clarification needed] und Bündnis 90/Die Grünen, 25.1%) with 19.4% of the votes and before Thede Boysen (SPD,[clarification needed] 18.2%).
[3] Faber succeeded previous lord mayor Klaus Tscheuschner on January 15, 2011[4] who didn't run for the post again.
Faber thinks that Flensburg's location at the Danish border is the town's biggest chance.
