William is very patient and also very supportive. If I don’t express something clearly, he will guide me through it with great patience. He’s also a great conversationalist and has a good sense of humor. When I’m in his class, I never worry about running out of things to talk about. He’s also very open to sharing his own life experiences and stories, which makes for great conversations. In fact, after his classes, I often find that I’ve not only improved my English — for example, he likes to teach slang and other natural expressions — but I’ve also gained something personally from the experience.

There is something effortlessly pleasant about talking to Bill -time seems to slip by unnoticed as conversations wander through all manner of topics and ideas. There is no pressure, no urgency, just a calm, easy rhythm that makes speaking feel natural. 🙂

I really liked Professor Billy. He's funny and entertaining. He has a wealth of knowledge to share with his students. It's a shame his schedule is always full. I hope I can have another class with him.

I’ve been learning English through online chat sessions with William for five years now, and I can’t recommend him enough. The experience has been absolutely fantastic—every lesson feels engaging, practical, and tailored to my needs. I’ve learned so much, from natural conversational phrases to grammar nuances that I never understood before. What makes the biggest difference is his teaching style: patient, encouraging, and always ready to explain things until I truly get them. He’s not just a teacher; he feels like a mentor who genuinely cares about my progress. Thanks to him, my confidence in speaking and writing English has grown tremendously. I’m truly grateful for all the progress I’ve made, and I owe it all to his dedication and expertise.

Willian是一个特别棒的老师，他总是告诉我要建立自己的自信，并且非常有耐心。和他一起上课，不仅能够学习到英语知识，还有很多人生哲学，是成长路上特别好的一位老师。期待下一次上课。

Aula maravilhosa, como sempre. Melhor professor! Adoro conversar com ele. Já virou um amigo!
