Our values

In our experience, Mutual Trust & Respect are the basis of everything in an organization. Without respect, there is no trust, and our approach aims to develop a culture founded on Mutual Trust & Respect in organizations. The cornerstone of a culture of Mutual Trust & Respect is openness among all functions and levels of an organization, as well as collaboration, which is so much more than just cooperation. Collaboration requires accountability for one’s own actions and empathy for others. Participation is the driving force for sustainable change and refers not only to the inclusion of employees in decision making but also to the collective effort involved in steering an organization in the right direction.

Our approach

We believe that one can only change what one truly understands. We therefore approach change by performing a deep analysis of an organization by means of desktop reviews, interviews, focus groups, 360° Feedback and employee surveys. We have a systemic and holistic view of organizations and design our change processes in such a way that they take all aspects, both tangible and intangible into account. To do this, we employ a diverse array of tools and methodologies but do not follow any specific ideology or management theory.

Tim Bookas

Founder, Partner & CEO

„Change is the common denominator for everything we do. And no matter what the industry is nor what the challenge is, at the end of the day, it is all about people. And I am passionate about helping these people understand the need for change, the role that they can play and the benefits for them and their company. “

Cassandra Louw (PhD, PMP®)

Project Management Officer (PMO)

“In my work with Clients, I analyze their situation to identify the mindset, behaviors and processes that cause inefficiency and lower performance. By means of open and frank communication and a focus on efficient processes and procedural fairness, it is possible to overcome the internal friction that results in poor organizational performance. When an organization and its culture is positive and constructive, employees are proud to play an active role in its success.”

Nathalie Seifert


“My Consulting approach focuses on putting the individual at the center, and to understand his/her needs and motivations. A Consulting process is not successful when the processes and structures of an organization function perfectly, but only then when employees at all levels of the organization have the opportunity to further develop themselves and are motivated in their daily work.”
