Built by trial lawyers.
Feared by defendants.
Stinar Lannen, PLLC leads mass and class actions and tries bet-the-company cases. We represent publicly traded companies, business owners, and tens of thousands of survivors of abuse harmed by institutional negligence, data conversion, and mass wrongdoing. Founded by Parker G. Stinar and Patrick C. Lannen—recognized leaders in class and mass action litigation and complex business disputes—the Firm is built on more than $1.5 billion in sexual abuse global settlements, more than $50 million in verdicts in business trials.
Our attorneys have been appointed to leadership positions by courts across the country in some of the most consequential litigation of our time, securing eight-figure verdicts at trial and achieving landmark recoveries in cases involving institutional sexual abuse, physician misconduct, cybersecurity failures, toxic exposures, and high-stakes commercial disputes.
With offices in Los Angeles, Detroit, Denver, and Chicago, Stinar Lannen has nationwide reach. Our team includes former BigLaw equity partners, but we remain compulsive about providing the touch, precision, responsiveness, and agility of a tailored practice. We do not shy away from the courtroom—our willingness to try cases to verdict gives our clients a decisive advantage at every stage of litigation.
At Stinar Lannen, we combine the resources and sophistication of a major national practice with the responsiveness and personal attention of a specialized practice. Our clients are not case numbers; they are individuals and organizations whose lives and livelihoods depend on the outcome of their legal matters. We approach every engagement with the rigor, creativity, and relentless preparation that complex litigation demands.
Two disciplines. One relentless standard.
