Complexity motivates Andreas Wartenberg. That’s why this expert in technology management and digitisation loves working with people. His focus is on executive search. Because it is precisely at the top management levels that the most diverse characters meet. This harbours enormous opportunities, but also a potential for conflict that should not be underestimated. 

As a member of a very heterogeneous yet well-functioning management team, he has played a key role in shaping Hager Unternehmensberatung for more than ten years.

More than 25 years of personnel consulting, ten years in management and his distinctive goal and action orientation make him a partner you can trust when it comes to finding the people you need to help shape your company’s future.
