About me

I believe in taxes,

that you understand before you pay for them.

Tax advisor? Absolutely, and with conviction. What began as a detour through the insurance industry became a calling: a knack for numbers, a joy in complexity, and a desire to shape things. I've been with Tretor AG for over 20 years, as a partner since 2008, and a federally recognized tax expert since 2010. What drives me: tax law that is constantly evolving, and clients who stand to benefit from it. Contact me if you're looking for tax planning that truly makes a difference.
