About
Engineer, then advisor
My path is anything but a straight line, and that’s precisely what makes it strong.
Engineering taught me to break down complexity, to test every assumption rather than accept it, and to think long-term. Finance taught me that numbers only really matter once they meet real life.
It’s also what shapes how I work with the German system. It isn’t more complicated than any other, it’s simply built on rules most of my clients didn’t grow up learning. My job is to make them legible, then decide with you.

What doesn’t change from one case to the next
Three principles, and what they change in practice
1
No exclusive ties
I work with several partner banks and insurers, exclusive to none. No quota, no house range to defend. The difference is verifiable in the public register, not just claimed on a website.
2
Compensation before the recommendation
You know how and by whom I’m paid before the first meeting, not after. Commission from a provider or a service agreement: the calculation method is written down, and it comes before the advice.
3
One point of contact, over time
No changing team, no file handed off. Your situation evolves, and the strategy evolves with it. That’s why I deliberately limit the number of cases I take on.
Beyond advising
What else drives me
When I’m not working with my clients, I’m usually on a bike, on a trail, or in the middle of a triathlon training block. Endurance sport has taught me more about wealth management than any textbook: both reward preparation over impulse, consistency over intensity, and a clear head when conditions get rough.
I also have a soft spot for classic cars, for engineering built to last. An attitude that shapes my work too: I want to design financial plans that hold up just as well.
