Our firmwide, interdisciplinary collaboration is integral to our understanding of the legal and policy frameworks in which complex business and legal issues arise.

In every aspect of our work, we stay true to the firm’s core values: providing exceptional client service; enhancing lives in our communities; prioritizing a collegial work environment; and fostering a diverse workplace through our unyielding commitment to inclusivity.

Commitment to Excellence

Renowned for our tradition of exceptional client service across more than 40 distinct practice areas and industry groups, our lawyers are globally recognized as market leaders. We offer novel and industry-focused services, ensuring our clients’ interests are represented effectively and align with their business objectives.

The foundation of our continued success is an extensive array of experience from both the private and public sectors, which informs every aspect of our practices. The backbone of our regulatory practice is built on the experience of many former senior U.S. and European officials from regulatory agencies and governmental departments. A substantial number of former federal and state prosecutors are members of our leading litigation practice, which includes globally recognized disputes practitioners, and a highly regarded international arbitration team. Our deep transactional bench spans numerous industry disciplines and draws from a wealth of in-house experience.

This diversity of backgrounds and skill sets amplifies our understanding of the most effective ways to structure transactions, resolve complex legal disputes, and address regulatory challenges.

Firmwide Sustainability Mission Statement

Empowering Our Communities

Pro bono is at the core of who we are as a firm.

From our early days arguing for a right to counsel in the landmark Gideon v. Wainwright, to defending the rights of those persecuted during the McCarthy hearings, to securing the right to vote in recent elections, we are driven to ensuring equal access to justice. Our ongoing dedication is most recently exemplified by the more than 100,000 hours of pro work we provided in 2024.

Our lawyers around the globe deliver extensive pro bono services that include cutting-edge impact litigation aimed at the equitable application of the rule of law, individual representation for people who cannot otherwise afford counsel, regulatory and public policy advocacy, and nonprofit counseling. Learn more about Arnold & Porter’s commitment to pro bono.

Our lawyers and professionals possess a multitude of diverse life experiences and perspectives, which inspire the creativity and problem-solving we deliver to fulfill our clients’ needs. We work diligently to foster a workplace that creates opportunities for our lawyers and professionals to thrive in their chosen career paths and enhance the lives of those in their communities.
