O’Brien Law Firm, a Missouri-based law practice established in 2000, focuses on representing individuals affected by mesothelioma and asbestos-related diseases. The firm has built its practice around investigating, prosecuting, and resolving asbestos civil cases and bankruptcy trust claims, while fostering ethical and compassionate client relationships. Located in St. Louis, the firm has positioned itself as a leading practitioner in asbestos-focused litigation in the Midwest and has expanded its expertise to include workers’ compensation claims for Missouri employees diagnosed with mesothelioma or asbestosis following legislative changes in 2013. In 2020, the firm broadened its practice to handle sexual abuse, criminal injury, serious injury, and wrongful death cases, continuing its work on behalf of clients harmed by the misconduct of others.
