Washington, DC, November 19, 2025 – Miller & Chevalier Chartered has been ranked 13th globally in the prestigious Global Investigations Review (GIR) 30 list, which recognizes the world's leading investigations practices.  

GIR lauds the firm's leverage of its "deep subject-matter expertise" and "strategically compact structure" to "deliver high-impact results across jurisdictions," noting that "the practice has evolved through integration rather than expansion, embedding niche expertise, such as workplace culture matters, business and human rights, and multilateral development bank investigations, into its core investigations offering."

"We are proud to once again be included in the GIR 30. This ranking reflects our continued success as Washington, DC’s powerhouse boutique, and our ability to navigate today's complex enforcement landscape," said William Barry, Chair of Miller & Chevalier. "What sets us apart is our client-tailored approach, combining scale with bespoke strategy and direct, hands-on engagement. In an era dominated by mega-firms, our clients value our accessibility and depth of experience."

About the GIR 30

Global Investigations Review's GIR 30 list ranks the best law firms for complex multijurisdictional corporate investigations, and the rankings are derived from an analysis of factors designed to measure scale, scope, and complexity of the matters the investigations practices have handled in the past two years, the firm's performance in those matters, and the recognized quality and substantive and geographic expertise of the lawyers involved.
