Learn English in a fun, engaging environment with a passionate and knowledgeable teacher

My son is very passionate about languages and loves talking about interesting words and often tells me stories about the English language. He made me interested with all the stories he has told me. I have learned a lot from him over the years. I think he will make a great teacher

Rolf is a very understanding gentleman, and he has a great enthusiasm for languages, both on a deep linguistic level, and in a fun and creative way that is accessible to all.

Great guy! I think his superpower is patience because he has helped me through a lot of my grammar mistakes without any judgement on his part!

I've had the pleasure of being tutored by Rolf in his computer science forte. He is a clear thinker, able to structure the narrative of a tutorial into clear and understandable components regardless of my level of naivete (which we see reflected in his writings). He doesn't let his own fascination with the subject derail the didactic component of the conversation into talking about his interests (a problem all too common in academia). He ever tries to be polite yet funny, which makes learning from him a delightful experience.
