I have been working with Annchen for over a year. When I started, I was looking for someone to help me improve my English fluency and confidence. Despite studying English for many years and using it daily at work, I still felt insecure in certain situations and often made basic grammar mistakes. Annchen understood my concerns and identified the areas I needed to work on. Together, we focused on these issues through practical activities and exercises. Additionally, she has been incredibly helpful whenever I have a presentation or meeting at work.
