“We’ve had some difficult cases and a lot of attorneys would just tell us what they thought we should do. David Pearce does an excellent job. He dug in and took responsibility. He was creative – taking the bull by the horns and adopting a real ‘let’s get this done’ attitude. David’s emails give us real analysis. We really felt he knew what he was doing and that he really understood what we needed. A lot of foreign attorneys will tell you what to do, but not why you should do it. David always explains why.”
