04 — Meet The Founder
“
I teach confidence, not just grammar.”
Hi — I'm Theo. With nine years of experience teaching English to adults across 15+ countries, I've worked with both everyday learners and professionals.
What I've learned? Traditional teaching methods often fail adult learners. Adults don't need more grammar drills — they need confidence, connection, and context.
That's why I created English is Fun Studio — a space where adults can learn English in a way that actually works for them. My approach is built on understanding, patience, and a whole lot of laughter.
When I'm not teaching, you'll find me exploring new cultures, reading, or discovering the perfect coffee shops around the world. I believe that life experiences make us better communicators — and that's exactly what I bring to every lesson.
English is Fun Values
What We Believe In
Confidence First

Personalization
