Supporting complex decision-making and development processes through evidence-based, fair, and economically robust approaches drives my thinking and actions in my responsibility at and for aestimamus. What motivates me most is advancing the combination of science and practice for the benefit and added value of our clients and participants—as a diverse and dedicated team.
Contributing to the goal of achieving an optimal match between individuals and positions—for both people and organizations—has motivated me for more than 20 years. Taking into account the diverse contextual factors of our clients continues to inspire me anew. Furthermore, I consider the connection between science and practice to be both highly valuable and beneficial for our clients.
In our top management assessments, in addition to a strict focus on role requirements, it is essential to combine hypothesis-driven and exploratory approaches while ensuring that the process reflects genuine business reality.
I am convinced that effective and value-based leadership is one of the key factors for sustainable business success in our time. High-quality management diagnostics—whether supporting selection decisions and/or the development of leaders—makes an essential contribution to ensuring this kind of leadership and thereby creates value both for organizations and for individuals.
Supporting leaders and organizations in achieving success through sound management diagnostics and systematic, modern talent development is my passion. I draw on my understanding of entrepreneurial action, a systemic consulting qualification, and more than 20 years of consulting experience in international contexts. Collaboration on equal footing as well as efficient and pragmatic processes are equally important to me.
In my work, a genuine interest in my clients’ requirements is central. A combination of analytical thinking, methodological expertise, a trust-based collaboration, and enthusiasm for tailored solutions forms the core of my approach. Personal development and organizational change are equally in focus.
I find purpose and motivation in my work—shaped by high quality standards and strong service orientation—through scientifically grounded, people-centered, and sustainable consulting, always aimed at generating added value for both individuals and organizations.
Psychologist specializing in Work, Organizational, and Business Psychology (M.Sc., Ruhr University Bochum). Areas of expertise include psychological (personnel) assessment, leadership, test development, as well as social, environmental, and positive psychology. Practical experience in the design and implementation of assessment and development procedures (individual and group settings), potential analyses, and academic research on (work) motivation and empowering leadership.
Managers possess exceptional qualities. I find it a fascinating task to get to know these individuals and to understand them from a psychological perspective, supported by my broad professional experience. Every day, I am inspired anew by the opportunity to help create the best possible match between a manager, a role, and an organization.
Selection processes are demanding and multifaceted—just like the people they affect. Scientifically grounded and standardized approaches help ensure structure and objectivity. I value the challenge of applying my theoretical insights from psychological assessment in practice. This transfer between theory and practice is a central motivation in my work.
Strengthening leaders in their effectiveness and thereby securing the long-term success of organizations is my central motivation. I am driven by making potential visible, empowering people in their development, and continuously enhancing the quality of selection processes through structured, evidence-based methods. This is always guided by a commitment to fair and respectful diagnostics and a methodologically sound toolkit that is continuously refined and developed further.
My motivation lies in supporting individuals and organizations through scientifically grounded personnel assessment in realizing their full potential. With a consistent focus on quality, I accompany processes from conception through implementation. I am particularly driven by aligning individual strengths with organizational requirements and thereby creating sustainable added value for both sides.
