His experience ranges from the development of corporate strategies and the establishment of new business areas to the business transformation of companies, as well as restructuring tasks or crisis management in globally operating technology companies. In the field of Service Excellence he can draw on a very broad and long-standing experience - his personal expertise ranges from the development of new business areas, to increasing efficiency, to optimizing customer orientation.

Jennifer Ruhfus (BSc.; MSc.)

comes from a very international background. She was born and partly raised in the US, finished school in Germany, graduated with honor in International Business from the University of Maastricht, Netherlands, and the University of New South Wales, Australia, and finished her post-graduation in Organization Studies from the University of Innsbruck, Austria. Next to her academic education she gathered fruitful work experiences in different fields. Her hobbies – team sports, mountaineering, and the outdoors – have led her to the world of consulting and training: five years as an independent process trainer in the outdoor field started her career. This experience, her academic background, her open-mindedness and her professional engagement were the perfect foundation for a consulting career at the Transformation Management GmbH. For two years as part of the core team she was able to work in numerous projects in Leadership, Talent Management and Outdoor Trainings while also driving the organizational development of the company. Now she is still a part of our extended team and supports us in diverse projects.


Stefan Hebecker

After finishing his degree in Economic Mathematics, Stefan Hebecker worked as a Senior Consultant at Arthur Andersen for energy supply companies and in the mineral oil industry. For more than 20 years he has had numerous leadership positions in Human Resources Management. Most recently he was responsible for the region of Germany/Austria/Switzerland as the director of Human Resources Management in one of the largest organisations of the mineral oil industry. In addition he was part of several supervisory boards.  

Along side the operational management of the HR department, following focus topics in strategic HR were part of his occupation:  

  • Talent and Succession Management
  • Performance Management
  • HR Organisational Development
  • Transformation and Reorganisation Projects

The close collaboration with the different organisational departments and their heads have always lead to practical and feasible solutions, which have further developed but not overstrained the organisation.

Johanna Widmann lives according to the motto "you are never done learning". Therefore, she has been gaining experience in companies since the beginning of her bachelor's degree - whether in small start-ups or large family businesses, both nationally and internationally (Thailand, Australia). These varied experiences and her openness to new things brought her to TMAG - as a dedicated working student parallel to her English-language Master's degree (Organization Studies). While working together in numerous projects, she was able to apply what she had learned. Furthermore, she gave us a lot of impulses by being the person she is and her dedicated contributions. Due to our successful collaboration, we are pleased that she is part of the expanded TMAG team.
