Our Approach

How We Work


We are tenacious and driven in everything we do. We run litigation teams that embrace flexibility, collaboration, and creative problem-solving at every step. Our uniquely nimble approach yields a more efficient operation and an impressive record.

How We Think


We know the law—we’re made up of former clerks, federal prosecutors, and federal judges; experienced trial attorneys; big-firm laterals; and top law-school grads. We thrive on challenges that require creative, big-picture thinking.

How We Treat People


We value empathy and integrity just as much as getting the job done. We don’t worry too much about hierarchy, which means we’ll focus on your case, not our egos. We provide responsive service.
