I'm constantly impressed with Bär & Karrer. They are timely, engaged and always to the point, so their answers are clear. Sometimes they also think outside the box, which is what we appreciate most. Whatever I said about the firm reflects how i see Cyrill. His client service and general level of service is very strong. His level of sophistication is very strong.
