Introduction
🗣️ Is your grammar solid, your vocabulary strong, your writing clear, but the moment you have to speak English out loud, you freeze up?

💼 You've already built a successful career. Shouldn't your English reflect that?

In 8 years of teaching English, I've worked with hundreds of accomplished professionals, and almost all of them tell me the same thing: grammar, vocabulary, and writing aren't the problem. Speaking is. That's exactly what my lessons are built to fix.

👨‍🏫 About Me

I work with professionals who have already built successful careers and need their spoken English to open more doors: better opportunities, bigger roles, more confidence in the room. You don't need another grammar drill. You need to actually speak, fluently and naturally, in the situations that matter for your career.

To understand English the way it's really used in everyday professional life, I moved to Peru to teach English in person, working directly with adult learners navigating real situations in a second language. That experience shaped how I teach: less theory, more practice.

📜 Qualifications

📜 120-Hour TEFL Certified
🗂️ 8+ Years of Teaching Experience
🌎 On the Ground Teaching Experience Abroad (Peru)
🎯 Specialized Focus on Speaking Fluency for Career Professionals

🎙️ My Teaching Methodology

✅ Conversational lessons that focus on talking through ideas and situations together, not listening to me explain grammar rules you already know on paper.

✅ Real life simulation, where we recreate the situations you'll actually face, like a negotiation, a job interview, a presentation, or a tough conversation with a colleague or client, so you practice the real thing.

✅ Real time correction, where I fix what doesn't sound natural the moment it happens and explain why, so you build instinct, not just knowledge.

✅ Lessons built around you and your goals, your industry, and your role, rather than a generic curriculum.

💬 What We Work On

🗣️ Speaking fluency and confidence
🎯 Sounding natural in real conversations
🤝 Professional speaking situations like meetings, interviews, negotiations, and presentations
⚡ Thinking and responding in English in real time, without translating in your head first
🙋 Breaking the habit of staying silent because you're not sure it'll come out right

🌟 Why This Works

You already know the grammar. You already know the words. What's missing is the repetition of actually saying them out loud in real situations, with someone correcting you in real time, until it becomes automatic. That's what every lesson with me is built around.

If you've hit a plateau where you understand everything but still hesitate to speak up, let's fix that. Book a trial lesson and let's get you talking.

🧳 Teaching Experience

I've spent the last 8 years teaching English, with a strong focus on working with adult professionals rather than beginners or students learning English for general purposes. Early in my teaching career, I moved to Peru to teach in person, which meant working face to face with adults who needed English for their actual jobs and daily lives, not just for a classroom exercise. That experience taught me how people really use a second language under pressure, in meetings, in interviews, and in everyday conversations where there's no time to pause and think.

Since then, I've continued working with the same type of student: people who already have a career, already know more English than they give themselves credit for, and just need the speaking piece to catch up. Every lesson I teach is shaped by that experience. I'm not guessing at what professionals need. I've watched it play out in real conversations, year after year.

🚀 Why Start Now

You've already done the hard part. You built a career, developed expertise, and earned your position. The only thing standing between you and the next opportunity might be a few seconds of hesitation in a meeting or an interview, when you know exactly what you want to say but don't feel confident saying it.

That hesitation doesn't go away on its own. It changes with practice, in real conversations, with real feedback, until speaking up feels automatic instead of risky. Every lesson you put off is another meeting, interview, or negotiation where you're holding back more than you need to.

You don't need to start from zero. You need focused, consistent practice with someone who knows exactly what's holding you back. Book a trial lesson and let's start closing that gap today.
