The combination will bring together two firms with deep roots in Phoenix and longstanding relationships with the businesses, industries and communities that have helped shape Arizona. Together, and operating under the Fennemore name, the firm will have nearly 300 lawyers and legal professionals in Phoenix and more than 800 across the firm.
“Both Fennemore and Gallagher & Kennedy have played an important role in the growth of Phoenix and Arizona for generations,” said James Goodnow, CEO of Fennemore. “It is rare to have the opportunity to bring together two firms with this much history, this caliber of talent, and such strong client relationships. We know each other, we respect what each firm has built, and we believe we will be even better together.”
For clients, the combination will mean access to a broader bench of lawyers and legal services, including Fennemore’s proprietary technology and innovation through Project BlueWave AI. G&K will bring established relationships and significant experience in natural resources, environmental, water, litigation, and business law, as well as an established New Mexico presence through its Santa Fe office.
“Uniting is a significant opportunity for our clients and our people,” said Kevin O’Malley, managing partner and shareholder of Gallagher & Kennedy. “Gallagher & Kennedy has built its reputation on strong relationships, practical counsel and a deep understanding of our clients and the communities we serve. Joining Fennemore will give our clients access to additional resources and capabilities, while giving two groups of people who know and respect one another the opportunity to work as one team.”
Together, Fennemore and Gallagher & Kennedy will create one of the most significant combinations in Phoenix’s legal market in years, laying the foundation for the future of legal service across the West and beyond.
