Meet
Mrs. Sierra

Hi there! I’m Sierra — a passionate, TESOL-certified English teacher with over six years of experience helping students around the world feel confident and excited about learning English.

I’ve taught in classrooms across Mexico and China, and now I work with learners of all ages, from energetic kids to driven adults preparing for big exams like IELTS and TOEFL. When I moved to Mexico, I had to learn Spanish, so I know learning a new language can be very hard. That's why all my lessons are encouraging and tailored to help you reach your goals, because I believe when you are learning the right way, it can be enjoyable and even exciting.

When I’m not teaching, you’ll find me traveling to new places, getting lost in a good book, or writing stories of my own. I love connecting with people from all over the globe, and I’d be so excited to help you reach your English goals.

Test Preparation

Whether you're preparing for the IELTS, Cambridge English, TOEFL- or other major English tests, I’ll guide you through exactly how the exams work. My lessons focus on real exam formats, timing, strategy, and scoring — so you’ll feel confident and fully prepared. I provide personalized practice, feedback, and tips to help you pass with success.

Free talk

Want to improve your speaking naturally? In my Free Talk classes, we’ll have engaging conversations on topics that interest you. I’ll gently correct mistakes, teach new vocabulary, and help you sound more fluent — all while keeping things relaxed, fun, and interactive. You’ll also get helpful feedback and optional homework to keep growing between lessons.

Business English

My Business English lessons are designed to help you communicate confidently and professionally in the workplace. We’ll focus on useful vocabulary, business phrases, email writing, meetings, and presentations — everything you need to sound polished and successful in an English-speaking environment.

Kids classes

I love working with children and teens! My classes are fun, creative, and full of learning — whether your child is just starting out or already speaks some English. Lessons include games, songs, reading, writing, and speaking activities tailored to their age and level, helping them build strong language skills in a joyful, supportive space.
