Since 1 April 2025, there have been some changes at Sigma System Audio-Visuell: Marco Vorderstemann and Stephan Nabbefeld are the new dual leadership team, setting the course for the coming years.
Together with owner and managing director Volker Schräger-Enkirch, a new management team is now in place that combines experience, forward thinking and a genuine hands-on mentality. The long-standing managing director will remain active in the company and will accompany the structural change with a clear vision and full confidence in the new team.
