Karen Seward and Kent Rowey, U.S. co-Chairs of Allen & Overy, congratulated the firm’s leading practices and individuals for their recognition “This set of U.S. rankings is further recognition of the high regard our practices and people are held in the market. Our investment over recent years has helped us recruit and develop the best talent, driving an increase in the number of ranked practices and leading individuals.”

Based in London, Chambers and Partners ranks leading U.S. firms and attorneys based on in-depth research and interviews with attorneys’ clients and peers. Chambers assesses attorneys on attributes most valued by clients, including technical legal ability, professional conduct, client service, commercial astuteness, diligence, and commitment. Most attorneys are ranked in bands of 1-6, with all band rankings considered to be a significant achievement. Some attorneys earn specialized Chambers designations including “Senior Statesperson” which indicates an attorney who no longer works hands-on with the same intensity but remains pivotal to the success of the firm, and “Star” individual, which is awarded to lawyers with exceptional recommendations in their fields. The Chambers USA guide is widely read by industry-leading companies and organizations nationwide. For more information, visit
