Theo-Chris Groenewald is a teacher, award-winning author, and content developer with over a decade of experience in high-stakes English education across four countries — South Africa, Kuwait, China, and Vietnam.

A published author — his book 雅思口语实用进阶指南 (IELTS Speaking Practical Advanced Guide), released by China Science and Technology Press in 2020, remains a practical reference for IELTS Speaking candidates across China — he has taught IELTS preparation at institutions across China and Vietnam, served as Head of Department for English and Liberal Arts in Shanghai, and directed his own language institute across China and South Africa. He holds IDP-certified teacher training qualifications in both IELTS Speaking and IELTS Writing, and conducts IELTS examinations weekly in his current role at Eastern International University in Ho Chi Minh City.

His ongoing research interest is the prosody and articulation of Asian speakers of English — what it sounds like when an idea is said not just correctly, but powerfully.
