Céline is a true professional in the area of voice- and presentation coaching. With a tailored and personal approach she provides very useful insights and techniques that really help in optimizing the way you use your voice in all kinds of situations. Celine is a real ambassador for the voice as an unique and beautiful instrument to express yourself in an optimal and powerful way.

What a wonderful and inspiring pleasure working with Céline. She is a truly amazing lady who knows her profession in every detail. She constantly triggers you to get the best out of your most beautifull instrument “Your Voice”. Isn’t it crazy that we hardly know what we can do with our voice and how we are able to improve the quality of speaking througout the day. She really opened my eyes and ears to the fullest. There is still soo much to learn that I can’t wait to the next training from Céline. I highly recommend her to everybody who needs a dedicated and very skilled voice trainer. Thanks for the great work you delivered! Warm thank you, Jos Frederiks 🙂

I attended Céline’s voice training. It was a great course which I recommend to everyone, even those with lots of public speaking / presentations experience. She takes the time to give personal attention and tips to each of the participants. And the whole course is full of techniques which everyone can apply on a daily basis. Furthermore, the atmosphere during the workshop is fun and friendly. If you want to communicate more clearly and more authoritatively, you should definitely attend this workshop!

Ze kan zelf erg goed stemmen imiteren, dat helpt bij de trainingen.
