Who will coach me?

I help adults speak English with confidence

I'm Brad Herdt, founder of ProVox and a certified English coach with over a decade of experience working with adults across Vietnam and beyond.

My approach is built on Communicative Language Teaching. This method is grounded in real conversation, not memorization or grammar drills. My goal isn't to help you speak perfect English — my goal is to help you become a skillful communicator. Each session is designed around how you actually use English: at work, in meetings, with colleagues, or in everyday situations where confidence matters.

I started ProVox because I enjoy seeing individuals grow into confident, natural English speakers. That's why I exclusively work 1-on-1 or in small groups. I take time to understand your world, and tailor each session to your real goals.

If you're ready to communicate with more clarity and confidence, I'd love to work with you.
