I’ve taken about 70 lessons with Lucas in both French (intermediate) and German (advanced). He’s always very professional, on-time, and attentive in our lessons. He customizes our sessions based on my interest and is always open to feedback. For example, he prepared a German vocabulary list of technical cameral gear and photography terms. This was so lovely of him to do in his free time prior to our session. Lucas is an excellent teacher with a fun and well-informed, providing interesting reading material and homework. Another time when Lucas really went above and beyond was when I started studying for the TEF IRN, which is a French language exam to apply for naturalization. Lucas had never taught this particular format of the exam before, and so kindly agreed to help me prepare for this new format. We went through countless exercises together and I was soooo happy when I aced my exam. 
 In summary, Lucas is an amazing teacher and I can genuinely recommend his classes.

Très bonne séance, comme toujours. On a discuté des langues, iTalki, et les différences entre les états des États-Unis. C'était une conversation formidable et très intéressant. Lucas connaît beaucoup à propos de n'importe quel sujet et, donc, c'est facile de discuter ce que ses étudiants aiment. À la prochaine!

You can't do better than Lucas, on iTalki or anywhere else. He's kind, he listens, he's a pleasure to speak to. I'd like to keep him a secret for myself, but I'm too late anyway—he's already booked like crazy, and for good reason!

Lucas is a great teacher. He has a wealth of knowledge he can share, is helpful and polite. He adapts his way of speaking and pronunciation to my current oral comprehension level. In my opinion his accent is worth acquiring, that is why I chose him in the first place. I am very content to have him as my teacher, because my active vocabulary increases with every session and my German accent atrophies steadily. Furthermore he keeps the conversation flowing and it is fun talking to him. I can recommend Lucas as a teacher to everyone who wants to improve, enhance and refine their French skills.

I've had about 18 months of French conversation lessons with Lucas starting from an A2 level. He is a very good conversationalist with an interest in a wide range of topics - history, science, politics, economics, culture. Lucas has a relaxed and easy teaching style that combines encouraging you to speak with gentle corrections. He is always careful to document his corrections of your grammar or vocabulary in the class notes so that you can practice on improving later. He's really helped me over the period, especially with some of the more difficult French grammar constructions. I highly recommend him for beginning/intermediate level French conversation.
