HR Leader | Global HR Business Partner @ Brenntag

About

As an internationally experienced, multilingual HR expert, I combine strategic personnel management with in-depth expertise in transformation processes to successfully guide organizations through change and growth. My focus is on developing high-performing teams, nurturing talent, and creating sustainable structures that meet today’s demands for agility, digitalization, and cultural diversity. In my role as HR Leader | Global HR Business Partner at Brenntag, I serve as a key sparring partner for top management in implementing strategic HR concept - from planning to execution. I cover the entire employee lifecycle and support critical areas such as project management, mergers & acquisitions (M&A), carve-outs, change management, and organizational development. My emphasis is on end-to-end processes: from initial concept to successful implementation. With solid experience in transformation management and change management, I guide organisations through digital and structural changes while fostering a culture that prepares employees and teams for future challenges. I develop tailored solutions for companies undergoing strategic transitions, whether it’s restructuring after mergers, building new business units, or optimising existing structures. Since 2019, I have been offering individual coaching and team development programs as an ICF-certified coach and entrepreneur, helping leaders and teams thrive in dynamic and rapidly changing environments. My focus is on resilience, leadership empowerment, and the sustainable implementation of change initiatives. In my free time I love to actively row on lake or river.
