Meet Helen von Dadelszen:

Helping thoughtful professionals speak with more clarity, confidence and presence

I work with capable, thoughtful professionals who have something important to say, but do not always feel confident saying it.

Many of my clients are international professionals, researchers, NGO and non-profit leaders, specialists, coaches, entrepreneurs, managers and emerging leaders. They are often doing meaningful work, but when it comes to presenting, speaking up in meetings, pitching ideas, leading conversations or communicating in English under pressure, things can feel harder than they need to.

They may speak too fast. They may lose their structure. Their voice may not reflect their confidence or expertise. They may get nervous, go blank or struggle to sound natural and credible in English.

That is where I come in.

I help people communicate clearly, speak with confidence and get their message across in a way that feels human, practical and authentic.

My approach

Communication is not just about finding the right words.

It is about your message, your structure, your voice, your body, your nerves, your audience and the confidence you build through practice.

In my coaching and workshops, we work on the whole communication picture. We might clarify your message, shape a presentation, practise answering questions, strengthen your voice, manage your nerves, improve your presence or help you feel more prepared for a specific speaking moment.

My work is practical, supportive and honest. I will not try to turn you into someone louder, shinier or more corporate. I will help you communicate in a way that feels clear, credible and like you.

Why this work matters to me

I believe that good ideas need good communication.

Too often, the people doing thoughtful, important work are not the loudest voices in the room. They may be working in health, sustainability, education, human rights, research, international organisations or social impact. They may care deeply about their message, but feel blocked by nerves, language, structure, visibility or the pressure of being watched.

I want to help more of those people speak up.

Not perfectly. Not performatively. But clearly, courageously and with enough confidence to be heard.

My background

I’m a New Zealand-born communication coach, vocal coach, speaker and facilitator based in Switzerland.

My work brings together a mix of experience in theatre, singing, vocal technique, English language teaching, HR, recruitment, non-profit work, event management, coaching and facilitation. That means I understand both sides of communication: the human side of nerves, voice and confidence, and the professional side of interviews, presentations, leadership, audience expectations and high-stakes moments.

I’m also an award-winning Toastmaster and a certified Roger Love Method voice coach for speakers. This means I bring practical vocal tools into my communication coaching, helping clients understand how their voice affects clarity, credibility, warmth and presence.
