I am a proficient English speaker who has years of experience communicating to people in English

I have a grade 4 for English on my Gcse and an overall distinction for GCSE speaking. So, these qualifications would allow me to help you, be the best you that you can be, and possibly be a proficient speaker. With my lessons, you would have more confidence, speak coherently and write coherent sentence structures.
And during my lessons I would not shame you for getting things wrong because that is how you would be able to learn and grow. Also I don't do favouritism and just like I would treat you with respect, I would expect you as a student to do the same and to other students that may join the lesson.
In weeks and or even months, you would no longer feel shame about your speaking skills and or writing skills, instead you would be able to write and speak coherently whether to a stranger, family member, colleague and feel understood not misunderstood.
My lessons does not just focus on enhancing your speaking skills but your writing skills so you feel confident again. The skills would be useful in all aspects of your life.
