Passionate ESL Teacher & Life Coach – Helping You Achieve Fluency and Confidence

With 17+ years of experience in teaching English as a Second Language (ESL), I specialize in making learning effective, engaging, and tailored to your unique goals. Whether you're an adult preparing for an exam, a professional needing business English, or a parent looking for fun, interactive lessons for your child, I provide customized lessons that deliver real results.

My expertise includes:

✔ Exam Preparation (TOEFL, IELTS, CAE, FCE, PET, KET) – Proven strategies to help you succeed.

✔ Business & Academic English – Coaching for presentations, interviews, and professional communication.

✔ Young Learners (ages 4+) – Playful, dynamic lessons for kids (Starters, Movers, Flyers).

✔ Language Coaching Integration – For students who want language learning combined with personal growth, mindfulness, and confidence-building.

I hold the CELTA certification (Cambridge’s gold-standard teaching qualification) and have worked with institutions like The British School Rio de Janeiro, designing courses that empower learners. Beyond traditional teaching, I focus on real-world communication, helping students gain the skills they need to thrive in academic, professional, and everyday settings.

As a certified language coach, I also support clients in goal-setting, overcoming challenges, and building resilience—skills that complement language learning. My approach is warm, student-centered, and results-driven, ensuring you feel motivated and supported every step of the way.
