Did you know your voice is like a fingerprint of your personality, authenticity and confidence? Often I see people who give their voice away because of too much pressure on the vocal chords. For this reason the message is not heard by the audience and a the same time it costs a lot energy to prove you are right.

When you create awareness on how to use your voice, you’ll discover a freedom in speech. You will be heard better and taken more seriously. The more the voice resonates, the more impact you’ll make.

In my practice I hear strong results of the voicework, especially in public speaking and private meetings, even at the kitchen table.


Katrien has coached me on the use of my voice… very remarkable, clarifying and effective… Recommended!”
