"It’s been 12 years since I started learning English with Teacher Jon. He didn’t just teach me English; he taught me life skills. He taught me how to use slang, write, and read like a native speaker."

Jon designs the lessons with a lot of humor and lightness, making it really fun! He is very motivated and infects you with his positive attitude. I especially appreciate that he places a lot of value on good expression. In case of uncertainties, he can even help in German and Swiss German. Thank you, Jon! :-)

"I had a lot of fun learning with Jon. He is friendly and tries to correct my speaking to be accurate and grammatically correct, and he also finds ways to connect between the student and the teacher to help us understand even better."

"Teacher Jon makes me feel that my English speaking will definitely improve."

"I have known Teacher Jon since my children were in kindergarten. At that time, I was searching for an English teacher whom I could truly trust-someone not only knowledgeable but also kind and patient with young children. From the very beginning, Teacher Jon has embodied all of these qualities. He has not only been caring and supportive but has also instilled in my children a genuine love for the English language from an early age. This early encouragement became the solid foundation that shaped their journey in English learning. Today, both of my children have greatly benefited from that strong beginning. My eldest successfully passed the entrance examination to the Police Cadet Academy, while my youngest is now studying at a high school in the UK, where she continues to progress rapidly in English. I firmly believe that the right teacher can be a life-changing role model. With Teacher Jon, my children received the best possible start - a foundation that will remain with them for a lifetime."

"I am really happy to have started a path of improvement with Kurt! He makes his lessons lively and interesting! Super welcoming but at the same time super professional! I absolutely recommend him!"

"Jon is a really fun tutor! He helps identify flaws and teaches how to correct speech as well. He also helps plan lessons that are suitable for our goals. What impressed me the most is that Jon understands Thai well, which makes communication smooth, and he can help adjust speech appropriately for exams or real-life use. Importantly, he has a sense of humor, making the learning atmosphere not boring at all. Learning with Jon is both fun and helps improve speaking skills!"

"Kurt is a great teacher. I enjoy his lessons and I can recommend him to anyone who wants to learn English. During the lesson, he corrects my mistakes, which I really like, and I am glad I found him. I believe our lessons will continue for a long time. I definitely recommend lessons with Kurt. :)"

"I had a lot of trouble speaking English because I was afraid of making mistakes. Jon helped me fix my pronunciation and grammar and made me feel much more confident. The lessons are fun, and he always talks about topics I'm interested in, like aviation. It's been a great investment for my career goals."

"I’ve really enjoyed learning with Jon because his teaching style makes every lesson engaging and easy to follow. He puts a strong emphasis on pronunciation, which has helped me gain more confidence when speaking English and go straight to what's really important for IELTS. I feel that I’m improving step by step, and he always gives clear explanations and useful feedback. Learning with him has been both helpful and enjoyable, and I truly appreciate his guidance."

"Studying with Teacher Jon made me develop my English skills by leaps and bounds. Looking back, I feel grateful to Teacher Jon for making me who I am today."

"Jon organizes the lessons the way I need them. Step by step, he makes me feel more confident with the language. And he does this in a humorous, friendly way. I will continue to book lessons and can highly recommend him"
