About O’Brien Law Firm
Founded in 2000, O’Brien Law Firm represents working people and families in serious civil cases with direct attorney involvement, detailed investigation, and personal accountability.
A focused team, direct attorney access, and trial-ready preparation.
O’Brien Law Firm was established to help people diagnosed with mesothelioma and other asbestos diseases. The practice later expanded to civil claims involving sexual abuse, violent crime, serious misconduct, and wrongful death.
The firm’s size is intentional. Clients should know who is handling the case, understand what is happening, and have meaningful access to the attorneys responsible for the work.
Serving clients in Missouri, Illinois, the Midwest, and selected matters across the country.
Familiarity with regional jobsites, trades, courts, organizations, and communities.
Concentrated civil practices instead of a high-volume, one-size-fits-all model.
Attorneys participate in investigation, strategy, communication, and resolution.
Case preparation follows the evidence, available law, and the client’s informed decisions.
How the firm prepares a serious civil case.
Listen
Understand the history, immediate concerns, and the client’s goals.
Investigate
Identify records, witnesses, products, institutions, and potential defendants.
Evaluate
Assess deadlines, jurisdiction, evidence, damages, and practical options.
Pursue
Prepare the claim carefully and seek accountability through the appropriate path.
Meet the people responsible for the work.
Attorneys, paralegals, investigators, and support professionals work together around a defined case strategy.
Clear communication and long-term relationships shape the work.
Former clients, labor organizations, community groups, and referring attorneys have played an important role in the firm’s growth. Many of those relationships began with one serious case and continued because people knew who was responsible for the work, received clear updates, and were treated with respect.
That history continues to shape how the firm serves clients today. The attorneys focus on careful preparation, candid advice, and direct communication so clients understand the next step, the decisions ahead, and the practical considerations that may affect the case.
The firm began with mesothelioma and asbestos litigation, exposure investigation, trust claims, and regional labor relationships.
The practice later added sexual-abuse, crime-victim, serious-misconduct, and wrongful-death claims.
Outreach, education, and long-term relationships support the firm’s work beyond individual cases.
The attorney’s role is to explain risks and options so the client can make informed decisions.
