What Clients Say

John is the smartest guy in the room and he pairs that intellect with an approachable demeanor and a keen feel for the intricacies of complex litigation that is extremely rare in a consultant/expert at his level. With his multi-disciplinary expertise, he is constantly looking for new angles and seems to deliver every time.

— Leading Litigator, National Law Firm

John and his team are amazing. They took one of the most scientifically complicated cases I’ve ever been involved in and truly figured out what happened. That was hard enough to do, but perhaps where they really shined was in explaining that science — first to me so that I could effectively question witnesses, and then in deposition — in a way and at a level that those of us who are not engineers could understand and follow.
