the voice behind the work
As a dialect coach and strategist, I help high-performing entrepreneurs refine their English to match their global ambition. If presence, clarity, and edge matter in your world — you’re in the right place.
When I first began learning English at age 12, I was taught grammar and vocabulary — but never how to sound like a native speaker. Every teacher I had carried a strong Swiss accent. And I was told — more than once — that true success in a foreign language wasn’t possible for someone like me.
I didn’t believe that.
So I built proof that said otherwise.
Through years of obsessive listening (thank you, Hollywood), I taught myself to hear — and replicate — the subtleties of native US American English. Not through shortcuts, but through relentless refinement. Sound by sound. Until what I said matched how I saw myself.
That discipline shaped more than my speech. It shaped the trajectory of my career.
Today, I coach high-performing entrepreneurs, creatives, and performers to master the mechanics of influence — starting with their voice. My method blends linguistic precision with performance psychology, helping multilingual professionals align their speech with the authority they already carry.
With a BA in English Linguistics from the University of Zurich and an MA in Voice Studies from the Royal Central School of Speech and Drama, I’ve trained native and non-native speakers alike — from stage to boardroom. I’ve coached actors for TV and musical theater, and I’ve helped entrepreneurs refine the final 5% of their accent to lead on global stages.
But my work isn’t about perfection.
It’s about presence — the kind that’s felt before a word is spoken.
If your voice still sounds like a mismatch to who you are, I’ll help you recalibrate it.
Not to erase your identity — but to unlock its full authority.

"I worked with Ronja on a production of Little Women at Trinity Laban and her brilliant accent work with the students was instrumental to their performances, not only helping them develop their characters even further but to also give them the confidence to use their voices. Ronja's enthusiasm, communication and support to the creative team was fantastic throughout the process."
