Firm Overview

Brown Rudnick LLP

Brown Rudnick represents clients from around the world in complex business transactions and high-stakes litigation. With relentless focus on our clients’ objectives, we assist with business-focused solutions that address today’s ever-changing, ever-demanding competitive marketplace.

In a world of mass legal service providers and anonymous corporate law firms, Brown Rudnick acts and thinks a little differently, serving our substantial client base from the world’s leading financial and technology centres.

Brown Rudnick is an international law firm with offices in the United States and Europe. Founded more than 70 years ago, Brown Rudnick has over 250 lawyers and government relations professionals providing advice and services across key areas of the law.

Clients have all the benefits of working with a global law firm but without the drawbacks of feeling like they are a “small fish in a big pond” or getting lost amongst endless red tape, layers of management, or need to “feed” multiple lawyers.

We do not strive to become a provider for “volume work” – instead we focus our energies on being amongst the very best at what we do, working on the most complex transactions and disputes.
