Fourteen Armstrong Teasdale lawyers and five practice areas across multiple jurisdictions have been recognized in the 2026 edition of Chambers USA: America’s Leading Lawyers for Business.

For more than two decades, Chambers has been highlighting top lawyers and law firms across the United States. Firms submit detailed information about their teams and areas of strength, followed by in-depth analysis and research including client interviews. Law firms and individual lawyers are ranked in bands from 1 to 6, with 1 being the highest. The qualities on which rankings are assessed include technical legal ability, professional conduct, and client service, among others. Exceptional Lawyers can also be ranked Senior Statesperson, Star, or Eminent Practitioner, and lawyers on the rise can be classified as Up-and-Coming, Associates to Watch, or Star Associates.
