Where I teach

My teaching runs across very different rooms, and that is deliberate. Each one teaches you something the others cannot.

  • From September 2026 - ESOL teacher in prison education, teaching English to adults
  • Summer 2026 - Senior EFL teacher, teaching multilingual groups of teenagers and supporting the coordination and management of the programme
  • 2025 to 2026 - EFL teacher at Kings London, teaching international adults and teenagers, and writing their progress and end-of-course reports
  • In Hungary - teacher at an English language school, and corporate and one-to-one business English for staff at E.ON, Strabag, Ganz Electric, Apcom, Konecta and Caffé Service
  • Since 2023 - freelance English teacher: one-to-one, small groups, company groups and online, in general English, business English and exam preparation

Qualifications

I hold the CELTA, the Cambridge qualification English language schools look for when they hire teachers, and passed Delta Module 1 in 2024. The Delta is Cambridge’s diploma-level qualification for experienced English teachers. I am now completing Module 3, which is about analysing what a particular group of learners needs and designing a course around it: the same thing a good one-to-one lesson does on a smaller scale.

I hold an enhanced DBS certificate and am registered with the DBS Update Service, which matters to parents of teenage students.

Before I taught

For five years I was a singer at the Budapest Operetta Theatre. A stage career is years of work on breath, voice, pronunciation and delivery, and on standing up in front of people when it counts. It is also where I first helped colleagues with pronunciation and the accurate delivery of text. That is the background I bring to presentation coaching, and to anyone whose English is fine on paper but deserts them when they have to speak.

I also spent several years guiding international scholarship students on the Stipendium Hungaricum programme, explaining history and culture to groups from many different language backgrounds. Most of teaching a mixed class is exactly that: finding the version of an explanation that lands for everyone in the room.

Earlier still, I ran administration and finance for a business travel agency - contracts, invoices, client and supplier correspondence - and later wrote English web content for an international software team. So when a business English student brings me a contract, a supplier email or a report, I have handled the real thing rather than a course-book version of it.

How I teach

A first lesson is mostly me listening. Before anything is planned, I want to establish what you can already do, which is rarely what a level label suggests.

After that, lessons are communicative and built around what you actually need English for. That means your own material where it exists - the emails you have to write, the meeting you found hard, the exam paper you have to sit - rather than the next unit of a course book. I keep notes on every student’s progress and adjust the aims as I go.

Written work comes back with an explanation of why something is wrong, not just a correction. A correction tells you about one sentence; an explanation tells you about the next twenty.

Languages

Hungarian is my first language, I work in English every day, and I hold a B2 certificate in German. I teach in English and in Hungarian: for a beginner, or for a point that is genuinely confusing, two minutes in Hungarian is worth more than a rule about immersion. And having learned English myself, I know from the inside which parts of it are hard.

Working together

Tell me what you want to be able to do in English and by when. I will reply with an honest view of what that takes.
