I began taking Gareth’s online English class last July. I am a tax professional and have lived in the United States for 15 years with a solid foundation in English. I wanted to further improve my pronunciation, grammar and significantly expand my business vocabulary in order to prepare myself for the next stage of my career. What truly sets Gareth’s class apart is how thoughtfully structured and personalized it is. Each lesson is clearly organized with specific objectives, concise takeaway notes, and targeted homework assignments. Gareth provides supplementary materials for review after class, which has allowed me to continue learning independently and reinforce what we cover during our classes. With Gareth’s guidance, my English has improved substantially. I now communicate with greater clarity, precision, and confidence in professional settings. I would highly recommend his class to professionals who are looking to elevate their English skills in support of long-term career growth.

For the past two years, Gareth has been an exceptional teacher for me. Every single lesson has delivered value—never a moment wasted. He creates an environment that’s both relaxed and empowering, making it easy to grow and push boundaries. His feedback? Always direct, always constructive, and delivered with precision and care. A true professional in every sense.

Gareth is by far the best teacher I've ever had on italki. I've had many teachers on this platform, but none of them comes close to him. His lessons are always really fun and enjoyable, and you learn an incredible amount in every class. I couldn't recommend him more!

Gareth always gives me valuable advice and offers great alternatives to improve my vocabulary. His teaching style is flexible and adaptable to different levels of English. The materials and topics we explore are wide-ranging — from culture and history to mental health and, most importantly for me, career development. No matter the topic, he can always help me whenever I get stuck translating from my mother tongue into English. I highly recommend you to choose Gareth as your English guru :)
