Dr. Wolf Pfannenstiel

As an enterprise- and solution-architect, Wolf Pfannenstiel is one of the “men staring at boxes” successfully for many years now. His motto is “Vision with Depth”. His working style is characterized by a fair balance of precision and pragmatism as required by the respective working context.

As a voluntary service, Wolf works for the counseling organisation “Adelante – Verein zur Unterstützung von Menschen mit traumatischen Erfahrungen e.V.” supporting people affected by traumatic experiences. He regularly practices meditation to achieve mental balance. Together with a friend, he leads a self-awareness group for men.

Dr. Nedialka Bubner

After receiving her doctorate in literature, Nedialka Bubner has been dedicated for more than 15 years to the area of Enterprise Architecture. She sees the harmonious and consistent interplay between architectural dimensions and business capabilities as an essential precondition to sustainable success of an enterprise – at any level and in any phase, from the strategic vision, via the operationalization path, down to the daily business.

Dr. Bubner’s core competence areas are Information and Data Architecture, Enterprise Architecture Design and Governance, Complexity and Interdependencies Management, Transformation- and Migration Strategy.

In her private life she is spending time with her family and her two Maine Coon cats. She likes traveling to countries near and far and exploring different cultures. Contemporary art and architecture, music, ballet and literature are key sources of inspiration and inner balance.

Dr. Thomas von Lingen

How should consulting excellence regarding corporate transformation look like? In the view of Thomas it starts always with a context oriented understanding of the topic in question and its well-defined scoping within the business model. Than the design of a sustainable target picture is to follow. The final step is defining a roadmap for a reliable delivery of the target picture along and across the relevant transformation areas (i.e. business case, organisation, technology, culture).

Thomas studied business administration at the Goethe University Frankfurt/Main. Consulting and project management are the two constants in his professional development. Furthermore he works as a lecturer at the University of Bayreuth and gives seminars relating to consulting and project management topics in cooperation with external institutions. His motto is as follows: „Be the change you want to see!“ (attributed to Nelson Mandela).

In the private spheres Thomas is addicted to music – both listening and playing (i.e. the six string).

Meaningful, effective, appropriate stands for our consulting standards as well as for our personal aspiration.

Andreas Garscha

Andreas Garscha has many years of experience as a management consultant in the organizational context, especially in the service sector, including financial services, professional services and telecommunications. He guided executives and teams in change programs with the goal to achieve set targets and ensure sustainability.


It is important to him to adapt successful methods to the individual customer needs and to implement suitable processes, organizational structures and performance management systems. His goal is always to enable the customer to an independent further growth and  sustainable development.


In his free time you can find Andreas very often in his garden, the garage or the Frankfurt city forest. After emotional roller coasters in his job or at the stadium of Eintracht Frankfurt, he gets the necessary balance from family, friends & the dog and in the restoration of old pieces of furniture. There is nothing more beautiful to him than the scent and feel of a freshly polished old wooden slab.

Holger Werner

After training and working within auditing in Germany and abroad for one of the big 4 auditing companies, the graduate economist Holger Werner took over the international structure and IPO of a music software company as CFO. Since then, he has been involved in founding, merging, restructuring and strategically realigning companies. In various executive roles, he was jointly responsible for the merger of two major German banks, built up a globally active shared service company for the world’s largest insurance company and digitised the corporate customer business of a leading private bank in Germany, with which he most recently founded a company to support German SMEs in their digital transformation.

Holger Werner has been Managing Director at Dangelmayer Seemann since February 2020 and, in addition to setting up the Stuttgart office, is pleased to be able to assist customers with his extensive experience in dealing with their strategic and operational questions. In addition to his family, his private passions include cooking and especially baking. His cheesecake is already popular across borders all the way to Australia.

Pia Weber

Originally from the banking sector, Pia Weber has been a member of the DANGELMAYER SEEMANN team since 2009 and, according to her own statement, greatly appreciates the professional and collegial atmosphere. As head of administration, she is the contact person for internal processes.

“Quality Time” is very important to her. She loves weekend trips with her camper van, likes to hike, but then has a hard time deciding between mountains and coast.
