I can use only superlatives to describe Marc. His work ethic, experience in industry or great communication skills during the project has been exceptional for us. Translating and proofreading our online tool to French language has been way more easier with this guy around! He didn't say a word to extra task from our side even when he was in the middle of writing his Doctor thesis - that just sumps up this guy pretty much. :) Can only recommend this guy and we would definitely work with him again. Thanks again Marc! :)

Marc has been a joy to work with, he is prompt, communicative, and always friendly. He takes constructive feedback well and is easy to direct. He will be a great asset to your team.

Pour la redaction du livre "Un canal de sang de Bâle à Paris", Marc Berrai a traduit de nombreux passages de livres en allemand. Ses traductions me furent très utiles, j'ai beaucoup apprécié son travail.

Marc has helped me with translations of several tricky technical texts, from English to French and/ or German, respectively. Always with great result and in short time.

Marc is always attentive to details, keen to keep deadlines and is pleasant to work with. I absolutely recommend him to anyone requiring reliable translation, yet rapid delivery.
