Student stories
Below you will find what our students say about our personalized English services — Private Classes, Business English Classes, Certification Classes, and Group Classes.
I already had a solid grasp of English — advanced level, by most measures — but very little real conversation practice. For professional reasons, I needed to change that, so I started private classes with Ketlyn. She assessed exactly where I stood and built a plan targeted at what I actually needed to improve.
Since I started my classes with Ketlyn, I have felt more comfortable and confident giving business presentations. I have also noticed significant progress in my English-speaking skills. A great teacher!
Ketlyn’s methodology feels truly friendly and adaptable, yet still highly effective. I feel truly comfortable speaking English and have passed all my Cambridge exams with high scores. I couldn’t ask for a better teacher.
I’ve been Ketlyn’s student for five years, and from the start she made me feel welcomed — more like a friend than just a teacher. I had studied English at a language school for four years before, but still had real gaps in my learning. Starting over at the basic level with Ketlyn, we worked through those gaps over time using games, readings, conversation, and correction whenever needed, with classes that always felt different from the last.
