Günther Weissenberger succeeds company founder Gerald Hanisch as CEO

Gerald Hanisch is withdrawing from the operational business of the RM Group and focusing on his role as owner. Mr Hanisch is and will remain “Mr Rubble Master” and will continue to represent the RM Group and, as founder, be the face to the outside world. Günther Weissenberger will take his place as CEO with immediate effect. Rudolf Schöflinger will take on the role of CSO, and Bernhard Fischereder will join as CTO on 1 June, rounding off the management team.
“RUBBLE MASTER has a very capable and committed management team with Günther Weissenberger at the helm, who know how to derive concrete steps from visions and successfully put them into practice,” says founder and owner Gerald Hanisch with conviction.
