We are guided by experience

The attorneys of Lewis & Llewellyn have over 150 years of complex civil litigation experience, ranging from "bet the company" litigation to discrete issues and disputes.

guided by experience

We are battle-tested and trial-ready

Unlike many of our opponents, we have tried dozens of cases and arbitrations. We bring that experience to bear at every stage of a case.

guided by experience

We offer innovative fee arrangements

While a traditional billable hour model is appropriate for some cases, it may not be the best option for all cases. As a firm, we are proud to offer a wide array of potential alternative fee agreements and are forging the path away from the billable hour in favor of other alternatives.

guided by experience

We staff to win; not to bill hours

At the outset of every dispute, we focus with laser-like precision on a path to victory. Our goal is always to win at a reasonable cost, and we stay focused on that goal throughout every stage of the case.

guided by experience
