> Duane Morris, LLP: A Law Firm Founded In Philadelphia In 1904

Our clients’ needs have changed dramatically since then. Our 21st century lawyers are more likely to negotiate multimillion-dollar transactions between global corporations or handle intellectual property issues regarding the licensing of biotechnology innovations.

From a partnership of four Philadelphia attorneys, the firm has grown to be among the 100 largest in the world, representing clients across an array of industries and from startups to Fortune 500 companies. Now with 29 domestic and international offices, no other Philadelphia-based law firm has offices in more cities worldwide. This network enables us to address client issues around the globe. Our legal representation in litigation, labor and employment, intellectual property, bankruptcy, construction, health law, immigration, and corporate matters has garnered numerous accolades from industry publications covering leading law firms and lawyers, and has earned distinguished recognition from major clients such as Cisco and TD Bank.

Our success is the result of a consistent, planned heritage of visionary leadership from the firm’s founders through the present day. Through their philosophy, Duane Morris has embraced a culture of inclusiveness, congeniality and consensus-building that is rare among law firms. This legacy continues under Matthew A. Taylor, who began his tenure as Chairman and CEO of Duane Morris in January 2018. While the partnership at Duane Morris may have grown beyond the founders’ imaginations, their spirit of unity and dedication to client service continues to guide our firm and shape our future.

In-House Collaboration

Throughout 114 years of growth, Duane Morris has always been guided by the same principles. At the heart of our firm is a partnership—an agreement to work together in the pursuit of client goals—bolstered by a foundation of collaboration and collegiality.

In 2013, Harvard Business School released its second case study of the firm, “Collaborating for Growth: Duane Morris in a Turbulent Legal Sector,” which is now taught as part of the syllabus at major business and law schools. As set forth in the abstract: “The firm’s uniquely collaborative organizational culture, which featured a transparent, data-driven compensation system, practice-group integration across multiple offices, and rewards for attorneys who shared responsibility, had contributed to the firm’s success as it had expanded into new U.S. and international offices.” Duane Morris lawyers team up fluidly across our global network, facilitated by technology and tools that enable easy collaboration, including dedicated collaboration spaces in offices across our footprint.

Our tenet of community and collectivity is reinforced by significant firm initiatives, including our Diversity and Inclusion Program, Women’s Impact Network for Success (WINS) and Pro Bono Program, as well as support for numerous industry and community organizations.

Supporting Our Clients

Duane Morris’ core philosophies have spurred innovative solutions and approaches to legal representation and client service. In one instance, our development of the Dispute Navigation Analytics (DNASM) technology helps clients assess risk, manage litigation costs and reputational exposure and enables earlier, more cost-efficient decisions for in-house counsel and executives.

Our business acumen and comprehensive and distinctive strengths in a wide range of legal matters have earned esteemed endorsements from general counsel and decision-makers at organizations with $1 billion or more in revenue. This keen insight into our clients’ businesses also enables us to regularly partner with them on other corporate and community projects to further their business objectives and reach our mutual stakeholders. As a leader among law firms seeking to advance diversity and inclusion initiatives, Duane Morris is often approached by clients seeking the firm’s assistance in developing their own diversity and inclusion programs.

Through our pioneering Diversity & Inclusion Advancing Leadership (DIAL) Toolkit and years of experience in this field, along with the firsthand knowledge gained from development of our own successful diversity and inclusion program, Duane Morris assists organizations in creating and sustaining a program that allows them to derive the benefits of diversity and inclusion.

The firm’s Women’s Impact Network for Success (WINS) is committed to fostering opportunities for, and enhancing the development of, its women attorneys.

Duane Morris’ Diversity & Inclusion Program regularly hosts events and panel discussions to continue its tradition of leading efforts to improve diversity in the legal community.
