Native speaker of English from California with an MA degree in teaching English to speakers of other languages and more than 20 years of experience teaching English

I would definitely recommend Chris to those who want to learn lively, conversational, but at the same time grammatically rich, literary English.
We studied the language intensively for about a year and a half, and I made incredible progress during this time. And I continue, although less frequently, to study with Chris to maintain my language at a good level, but also because I really enjoy our lessons. Chris is not only a top-notch professional but also an outstanding personality. Starting our lessons with him was the best decision I made.

Mit Chris verbindet uns eine langjährige, fantastische Zusammenarbeit: Als Übersetzer, Proofreader deutsch-englisch liefert er zuverlässig stets überpünktlich perfekte Arbeit, egal ob Texte für Marketing, Telcom, fachtechnische Inhalte, Untertitel.
CAT-Tools sind für ihn kein Neuland (Computer Assisted Translation).
Die Zusammenarbeit mit Chris macht Spass, auf seine ausserordentliche Flexibilität, nicht nur im Timing, ist zu 100% Verlass. Dabei lässt er seine Erfahrung als Lehrperson einfliessen, und bringt sich in beiden Sprachen mit guten, wertvollen Inputs, simpel erklärt und auf den Punkt gebracht.
Ein Perfektionist mit Charme. Eine Lehrperson wie Chris, kann man sich nur wünschen und weiterempfehlen.

I have known Chris for more than 15 years, and he is one of the most conscientious people I have met. He has always aspired to perfection in the editing and translation he has worked on with me. He brings the same desire for perfection to his ESL teaching. Chris not only prepares thoroughly before his classes, but also spends time after them to summarize lessons for his students, to reinforce the learning process. In his many years of teaching, Chris developed his own ESL materials when he felt those available for sale or in language schools did not provide what his students needed most.

Chris is a relaxed and friendly person, but he is not casual in the way he approaches his teaching and other work. If you truly want to improve your English ability, Chris will work even harder than you to help you reach your goals in speaking, reading, or writing, and in formal speech, technical terms, or slang.
