The Standard

Every claim gets a grade.
Every protocol, a source.

The same standard I hold at the bedside, applied to everything I publish here — mechanisms shown, sources cited, uncertainty named where it belongs.

The Story

Built on a legacy.
Driven by evidence.

My father founded Klinik St. Georg in 1991 as one of Europe's first hospitals to bridge conventional and integrative medicine. He treated patients from over 90 countries.

Today, as Chief Medical Officer, I continue that mission with a new generation of tools: peptide therapies, advanced diagnostics, and precision immunology. The medicine has evolved. The philosophy hasn't.

This site is where I share what I learn — the mechanisms, the clinical observations, the protocols that work. No hype. No miracle claims. Just the science, explained clearly.
