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. “

Nathalie Seifert


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

Philip Gisdakis

Working Student (Master Conflict Research/Bachelor Economics)

“For me, sustainable change always begins and ends with people. Therefore, understanding people and their conflicts during change is particularly exciting for me. Social science and economic perspectives thereby form my passion to apply what I have learned as working student in exciting projects.”

Melanie Kirr

Working Student (Bachelor Business Psychology)

“The fact that change is unavoidable in today’s world is for example shown by the ongoing rethinking from “survival of the fittest” to “survival of the best adapted”. For these adaptations/changes, a special focus lies on the people factor in organizations. As a student of business psychology, I daily learn how complex the human factor is, and how the how the experience and behavior of individuals reflects in an economic context, affecting how individuals react to change. For me it is so exciting to work practically on projects in which companies are advised on this important change management issue.”

Sara Alfirev

Working Student (Bachelor Psychology)

“My studies in the field of psychology and the intercultural experiences I have had, motivate me to better understand people around me, the processes and behaviors involved in their engagements, and myself. My area of interest is directed towards work and organizational psychology. Thus, having had the opportunity to be a working student at Breitenstein Consulting has allowed me to start fulfilling the goal of understanding and helping others improve and develop themselves and their work environments.”
