I would recommend Jurgen Roos in particular because he was very professional, knowledgeable, efficient, friendly, and helpful. He did an excellent job and all communications with him were clear and informative. His command of English was also excellent, so I would not hesitate to recommend him to other expats or English-speaking colleagues. I was impressed with his work; he explained things well and there were no surprises. 10 points for Jurgen!
