We provide the full breadth of legal resources to represent all of our clients' interests. Through interdisciplinary collaboration and specialized experience in our clients' industries, we offer truly innovative and effective solutions that align with both clients' short- and long-term business objectives.For those clients who cannot afford legal counsel, we maintain a broad and meaningful pro bono practice. Arnold & Porter is one of a small number of firms whose attorneys consistently average more than 100 hours per year of pro bono work. With a lengthy record of excellence, we remain committed to the community at large. In all of our work, we stay true to our core values. We maintain a diverse workplace, a collegial work environment, and an unyielding commitment to inclusiveness.
We set our standards high, expect the best from our attorneys, and return top-tier work on behalf of our clients. Our tradition of excellence is distinguished, and our attorneys are widely respected in the US and abroad. Our attorneys are leaders in their fields, speak frequently throughout the world on the firm's core practice areas, and are published widely in legal journals, industry and mass media, and "hot topic" books.
Our attorneys’ accomplishments are grounded in their training—often at the most noted legal institutions around the globe—and further enhanced by the experiences many of them had as doctors, biologists, chemists, public policy professionals, and former high-ranking officials from key US regulatory agencies and the executive and legislative branches of the federal government. Their insider perspectives are integral to understanding the legal and policy frameworks in which complex business and legal issues arise, and how best to structure transactions and overcome litigation and regulatory challenges.
