Summary

I get companies and processes rolling again when they are stuck.

I take responsibility when production lines are idle, supply chains stall, or reorganizations go off track. I analyze, structure, and implement – fast, direct, and with measurable success.

As a German-American interim executive, I combine technical know-how with intercultural leadership experience. I bridge cultural and operational differences between Europe and the USA – as an implementer, translator, and doer.
