Company History and Business Evolution

Armstrong Teasdale LLP traces its roots back to 1901 when founding partners Frank W. Armstrong and John H. Teasdale established a small practice in St. Louis, Missouri. Initially focused on corporate law and litigation, the firm quickly gained a reputation for handling complex business disputes and representing local enterprises. Over the ensuing decades, the firm expanded its practice areas and geographic footprint, opening offices in Kansas City, Jefferson City, and eventually Chicago, New York, Los Angeles, and other major markets. A pivotal moment came in 1990 when the firm merged with the venerable St. Louis firm Hanshaw & Donaldson, significantly boosting its intellectual property and transactional capabilities. The early 2000s saw further expansion through strategic mergers with firms in Denver and Washington, D.C., enhancing Armstrong Teasdale’s ability to serve clients in energy, government contracts, and regulatory matters. In 2015, the firm launched an innovative legal project management initiative, becoming one of the first large law firms to adopt Lean Six Sigma methodologies for efficiency and cost control. The 2020 acquisition of a boutique litigation firm in Los Angeles strengthened its entertainment and media practice. Today, Armstrong Teasdale LLP continues to evolve, embracing technology through AI-driven document review and virtual deal rooms, while maintaining its core values of integrity, client service, and community involvement. The firm’s history is marked by a commitment to adaptation and growth, evidenced by its steady climb in the Am Law 200 rankings and its recognition as a top workplace for women and minorities. From its humble beginnings in a single office to its current status as a national powerhouse, Armstrong Teasdale LLP’s journey reflects the resilience and vision of its leadership.
