Amazing, professional, kind, caring and punctual; these are just some of the words that come to mind when describing Christian. It’s a pleasure to work with him on a weekly basis. Through every lesson you can just feel the care that he has for each and every one of his students. I highly recommend Proton and Christian to everyone! He’s trustworthy and definitely knows how to get the best out of me. Christian motivates me and encourages me to reach my personal best. The frequent practice exams as well as the numerous workshops that are held every month are always an enjoyable lesson, where we revisit necessary skills needed for reading, writing and speaking the language. My friends and I really enjoyed attending them as they were all insightful and productive. Thank you Christian! Thanks Proton!
