About me.

I coach professionals to speak fluent English.

I'm David Mangene...

I'm a business English fluency coach, performer, and passionate teacher, helping professionals speak English with confidence, present with clarity, and profit in the international arena. 

I'm originally from the Boston area in the United States,

but I’ve lived in the Netherlands for over 30 years, and I’ve made it my mission to help international professionals unlock their English voice.


Teaching lights me up. Nothing frustrates me more than seeing talented people stay quiet, or lose deals, because they’re unsure of their English.


That’s why I do what I do: to help you speak up, stand out, and step into your next opportunity.

How I help you speak with confidence.

✅ Confidence First

We start with mindset and clarity, so you’re not just translating, you’re owning your voice.

🎯 Business Skills Second

You’ll learn how to present, pitch, negotiate, and communicate like a pro.

🧠 Grammar Last

Only the grammar you need, no overwhelming theory, just practical tools that serve real-life communication.

What some former students have to say...

I did some training with David a while back, focussing on getting some Swag. David did  a really good thing! I dare to say that I am fearless in speaking my pretty mediocre level of English now. It is a great relief to not give a shit anymore about mistakes and faults. It helps a lot in focussing on having impact with my workshops. Txs David!
