Executive Coaching

My coaching offering encompasses work with individuals and organizations. This complements Change Management processes, where requirements for organizational change go hand in hand with the need for the change of individuals. I have served in technical and non-technical roles with growing responsibility across the organizational hierarchy in large multinatonals to large “Mittelstand” companies, SMEs and startups. I experienced the needs and limitations of each role and can empathize with the individuals in those roles – I speak their language.
