Dipl. Wirtsch. Ing., Dipl. Bw.
After several years as a consultant Martin Sonnert held different executive positions within international corporations. Mr. Sonnert is focusing on the following topics:
- How can strategic succession and talent management really be managed successfully? Why is it so difficult to establish a performance management within a company which is totally accepted by all?
- How can new organizational structures – such as approaches like Holacracy, self organisation, networking, two parallel operating systems – be implemented comprehensibly and equally pragmatic, efficiently and effectively within encrusted structures?
- How can companies ensure to really institutionalise joint thinking, common exploring and collaborative learning?
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.

Before joining TMAG, he had been working as Head of Human Resources and Cultural Development at a large public corporation for many years. Therefore, he is also familiar with the challenges of day-to-day leadership and strategy development.
Empathy, acceptance, openness and sometimes "holding up the mirror" are indispensable ingredients in his consulting work.
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.
