Who We Are

Founded in 1984 by three litigation attorneys from a major Philadelphia law firm, Conrad O’Brien has established itself as the insider’s law firm—winning bet-the-company cases for AmLaw 100 firms and Fortune 500 companies, as well as high-stakes cases for government entities and individuals. Our attorneys are adept at resolving clients’ matters behind the scenes, but when that’s not possible, we do what we do best: take the case to trial and win.
