Hello, I'm John, originally from New Hampshire, where I spent 11 years before relocating to Texas for several years. Currently, I am pursuing my passion for aviation with the goal of becoming a pilot. Alongside my studies, I have been teaching English online for over 7 years, a role I thoroughly enjoy. As a TESOL-certified instructor, I specialize in helping adult learners achieve conversational fluency and excel in exams like IELTS and TOEFL. I take great satisfaction in meeting new people and supporting them in reaching their language goals. Outside of teaching, my interests include travel, sports, films, and music—topics that often enrich our lessons. I exclusively work with adults.

John is by far one of the best teachers on Italki! He helped me prepare for my TOEFL exam, and in just a few months, I went from an average school level in English to being able to speak with confidence. He is very patient and kind, creating a comfortable atmosphere for speaking. His lessons are always tailored to address your weak points, making every session productive and effective. Each of his lessons strikes the perfect balance between professionalism and a friendly atmosphere. It's always a pleasure to have classes with him. I highly recommend him!

Amazing as usual! One of my favorites native tutors so far, one of the few people who can lead the lesson and let me focus on my speaking and not on the control 💪🏻💪🏻💪🏻

I really enjoyed this lesson. The teacher was very attentive and supportive, listened carefully, and gave clear, natural feedback. The lesson felt relaxed and motivating, and I’m looking forward to the next one.
