Founded by Jeff Lau in 2011, Mastering Grammar offers editing, proofreading, and private or small-group tutoring services.

Mastering Grammar is not just about teaching grammar. Although this was the case at its inception, the range of teaching has since expanded to encompass all aspects of the English language.

Here you will find a wealth of information about English learning, resources for language exam preparation, information about my editing and proofreading services, as well as details relating to lessons and courses that can take your English to the next level.
