ISO 9001:2015-certified Quality Management System
grenke’s quality management processes have been certified to the ISO 9001 standard since 1998. We keep our improvement processes going with training and internal information sessions. Regular audits and re-certification by our certification partner, TÜV Süd, ensure that our quality management system is always up to date.
