Conrad O'Brien

At Conrad O'Brien, we tackle complex cases with tenacity and serve clients with responsiveness and integrity. Our uniquely agile, collaborative approach to litigation allows us to solve client's problems. Whether it's successfully taking a case to trial or preventing legal problems before they occur, we perform with the smarts and tenacity of a special-ops team. 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.
