As a multilingual Business English Trainer and Communication Coach, I bring more than 20 years of professional teaching experience together with over 30 years of live performance experience as a musician.

Every training programme is tailored to the client’s language level, professional role, and communication goals. From building a strong foundation in English to mastering the advanced language required for meetings, presentations, negotiations, leadership, and international collaboration, the focus remains firmly on relevant, real-world communication.

Learn the language. Practice the situation. Build the confidence. Use it in the real world.

A while ago, I wanted to further improve my English and work towards the Cambridge English C1 Certificate.
... Learning the nuances of the English language from a native speaker was already really helpful. But JC also always managed to guide me in the right direction for the exam, switching between the different areas of focus and getting the right mix of explanations, training, and casual conversation.
...Through our combined efforts, I ended up exceeding my goal and achieved a C2 level instead of C1 - for which I want to thank you again, JC!
