I am very impressed by their focus when handling cases dealing with energy or environmental regulation issues that could potentially get costly if not managed carefully! They do things right from beginning to end making sure you understand everything they have covered thoroughly at every point along way as well make necessary adjustments during your case management or even after it is filed/disbursed!! My only suggestion would be - try them first before engaging another service provider! As stated above this lawfirm handled my insurance coverage matter (asbestos) involving several layers so i was really pleased throughout entire process. Boies Schiller Flexner is very knowledgeable, skilled, intelligent and has the highest integrity. We worked with them for a couple of years on a M&A deal in the US that was very complex. We found them to be very professional, knowledgeable and very good at what they do. The US-based M&A team at Boies Schiller Flexner was very responsive and helpful. We highly recommend Boies Schiller Flexner. There is nothing that we would change.
