Buffi Duberman

In international leadership, words matter. One misplaced expression can confuse a room – or compromise a deal.
Enter Buffi Duberman: the Netherlands’ most sought-after English communication expert, known for helping leaders sharpen their message, avoid hidden language traps, and speak with confidence across cultures.

In her high-energy keynote, Buffi takes the audience on a fast-paced tour through the do’s and don’ts of global English – from false friends to fatal translations. Insightful, practical, and wildly entertaining.

Buffi has spent over three decades at the intersection of language and leadership. Originally from Brooklyn, she’s coached more than 10,000 professionals worldwide, including boardroom executives, media personalities, and native speakers.

She’s written four books, advised on 15+ TV productions, and created Communication Nation – a global platform for strategic communication. She even holds the world record for the Largest English Lesson, delivered at Lowlands in glitter boots and a cape. Because clarity and charisma go hand in hand.

On stage, Buffi brings the perfect mix of expertise and bravoure. She speaks the language of leaders – but never forgets the human behind the title. Her keynote is a masterclass in international credibility, delivered with warmth, wit, and unmistakable presence.

After 45 minutes with Buffi, you won’t just speak better English – you’ll lead with greater impact.
