About
Peter Oliver Greza
Communication trainer, rhetorician and author based in Tübingen, Germany.
Since 2019 I have been working independently with leaders, teams, university staff, teachers and students. My business operates as Tua Res Consulting, with the motto: Tua res agitur – it is your cause that matters.
I combine classical rhetoric with the demands of digital communication and the communication-focused use of AI. My technical background from several years in IT support and my research on online presentations at the University of Tübingen inform every training.
„Communication is not only what is said, but also what is understood. That is why it matters to master the whole rhetorical toolkit. Not just the communicative hammer.“
Beyond rhetoric, I write fantasy: my novel “Eisiger Zorn” (volume 1 of “Aygens Kriege”, in German) was published in 2026. aygens-kriege.de (opens in a new window)
My approach
Experiential learning
Learning through direct experience. We practise rather than just talk about it.
Tailored to you
No standard programme: every training is built around the challenges of the participants.
The whole toolkit
From ancient rhetoric to AI: I use what works in your situation.
Career
