About Fluenity

A coach, not an app.

Fluenity is built on a simple idea: real confidence in English comes from real conversation with a real person — not an app. One coach, Mitch Decker, and students who stay for years.

The person behind Fluenity

Meet Mitch Decker

Founder & English coach

Mitch is an American who spent a full career in business — sales and sales management, and running companies of his own — before turning to teaching. He holds a BBA in Finance from Southern Methodist University and an MBA in Management from the University of Texas, Permian Basin, and has traveled to more than twenty countries.

He taught for three years in classrooms in China, then has coached online for seven years, working one-on-one with hundreds of adults from more than a dozen countries. He helps them use English for work, travel, moving abroad, and everyday life — and most stay for years.

In Mitch's own words

I'm a retired American businessman, and I've been lucky to work across a lot of industries — sales and sales management, manufacturing, retail, logistics, banking, oil and gas, real estate, semiconductors, and consulting industries — and to own a few businesses of my own. That real-world experience is what I bring to every lesson.

Mostly, I just enjoy meeting people from around the world — hearing about their lives and culture, and watching them grow. I love travel (more than twenty countries, and three years living in China), long-distance running, biking, camping, hiking, and reading. The best way to improve your English is regular, real practice — so let's talk.

In his students' words

He has so many experiences in his life. It's not only learning the language, but also getting inspiration from him. I always learn new ideas from him.
