I was born, raised and educated in the United States. I’ve been living in Vietnam since 2013. I currently live in Da Nang with my wife and two children. I have a Bachelor’s Degree in Business Administration. I have been teaching English since 2014 and I really enjoy my work. I like spending free time with my family, riding my bike, swimming in the sea, and playing games with my children. I enjoy writing and recording music in my home studio. I like to learn and be creative. I have a great sense of humor and love having fun. Let’s have some laughs together as you develop your English skills. I love the English language and am very passionate about teaching.

I've had a lot of lessons with Challis. I think that I've learnt new things after each one of them, because Challis will always give you feedback and correct you on your mistakes. So, to have a lesson with Challis is a very productive thing to do if you really want to improve.

Challis is one attentive, and friendly teacher. Every session feels like a warm chat with a friend. He listens and provides feedback right away and explains the concepts of grammar rules.

I wanted to learn English because I won the Green Card Diversity Lottery and planned to move to the US to find a job. In my first lesson, I couldn't even say my name. I didn’t speak English at all. But recently, I successfully passed job interviews at a FAANG-level tech company in the US, and now I'm already packing my bags for New York! Challis helped me improve my grammar, vocabulary, speaking, and listening skills, and gave me a deeper understanding of American culture. His lessons were always fun and incredibly valuable. I also want to mention that YouTube videos and TV shows weren’t helpful for me at all. The only thing that really worked was conversational English lessons with Challis. I tried other teachers, but their lessons just weren’t as effective.
