“As HR Director ad interim, Dirk Stoltenberg reorganized the human resources department of Worldline Switzerland over a period of 8 months and brought it to a completely new level from a professional perspective. At the same time, he successfully coordinated a restructuring program for DACH-region in which the workforce was resized in a socially acceptable manner. Dirk is an expert in his field and is characterized by his structured approach, high efficiency and excellent cooperation with different stakeholders. It was a pleasure to work with him and I can warmly recommend him to future clients.”

“Dirk has a very strong HR background that is routed in a strong business understanding and data oriented leadership. He derives operational impact from strategic and business acumen, understands the importance of aligning with his stakeholders and has at the same time strong viewpoints. He is open and direct which means that you get a clear picture of his view on the challenges and opportunities. He has very strong capabilities in execution and thrives in an environment where he can make things happen. Dirk started the HR transformation journey for us in Germany. He was part of the global HR Director Forum and interacted highly constructive in that context. I enjoyed working with Dirk and give him my highest recommendation.”

“By supporting our transformation, Dirk made a significant contribution to halting our decline in the profit margin during the growth phase and increasing our earnings back to former record levels. I would like to thank him personally and on behalf of the clinic for his help in identifying key inefficiencies, cost drivers and weaknesses that needed to be corrected, for example in organization and management, as well as his active support during implementation.
As the founder and director of the clinic, it was particularly important for me to have an honest and neutral personal sparring partner in Dirk during this phase. Thanks to the very personal and unsparing feedback and discussions with Dirk, I was able to improve alongside the challenges and develop further in my leadership, as well as allow for a necessary support of responsibility and implement a sustainable organization. As Dirk was very active with managers and employees, for example in workshops and in direct exchanges, it was noticeable that after a short time he acted almost as an integral part of our clinic and mostly independently in line with our mission, keeping us informed at all times.
We have regained our financial strength and profitable growth. In addition, we have become an even more effective team and have developed a management that takes care of the cost drivers in the organization and supports profitable growth.”
