About me

My lessons are designed for ESL learners — students who want to improve their English for real-life situations, not just for exams or textbooks. When you take lessons with me, you can expect classes that are interactive, practical, and focused on communication. I believe the best way to learn English is by actually using it — speaking, listening, and thinking in English as much as possible. So, I try to create a friendly and relaxed atmosphere where you can feel comfortable making mistakes and learning from them. In each class, we usually focus on a specific skill — it might be pronunciation, grammar, vocabulary, or conversation practice — but everything connects to real-life English. For example, if we’re studying pronunciation, we’ll practice it in full sentences, not just isolated words. If we’re learning grammar, we’ll use it in real conversations so you can understand how native speakers really talk. I also use interactive exercises, worksheets, and real-life scenarios. For instance, we might role-play ordering food at a restaurant, talking with coworkers, or chatting with friends at a party. I want my students to leave class feeling more confident to speak English in the world outside the classroom. Every student has different goals, so I personalize my lessons to fit your needs. Maybe you want to improve your speaking for travel, maybe you need English for work, or maybe you just want to sound more natural when talking with native speakers. Whatever your reason, I’ll adapt the lessons to help you reach your personal goals. Another important part of my classes is listening and pronunciation practice. I know many learners struggle to understand fast English or find it hard to sound clear when speaking. That’s why I include exercises to help you recognize natural rhythm, stress, and intonation. Over time, this helps your English sound smoother and more confident. Most importantly, I want you to enjoy learning English. I’m not just here to teach grammar rules or give homework — I’m here to help you communicate, connect, and grow as a person through language. So, if you’re looking for lessons that are practical, friendly, and focused on helping you use English in real life, I’d love to work with you.
