Thornton Law Firm LLP

For more than four decades, Thornton Law Firm LLP in Boston, Massachusetts, has been dedicated to standing up for individuals, families and communities affected by serious injury, toxic exposure and corporate wrongdoing. From our Boston headquarters, we represent clients across Massachusetts and throughout the country in complex personal injury and plaintiff-side litigation, combining deep legal experience with a strong commitment to public health and accountability.

Our firm traces its roots to 1978, when we began pursuing justice for individuals suffering from mesothelioma and other asbestos-related illnesses. That early work helped shape our long-standing focus on cases involving dangerous products, environmental exposure and large-scale harm. Today, our team of 19 attorneys continues to advocate for thousands of clients in a wide range of matters, including catastrophic injury, defective medical devices and pharmaceuticals, workplace exposure cases, and complex class actions.

Over the years, we have been trusted to take part in litigation with significant impact. Our work has included representing the commonwealth of Massachusetts in its landmark lawsuit against the tobacco industry, which resulted in a multibillion-dollar settlement, as well as advocating for thousands of individuals affected by asbestos-related diseases. We have also represented children affected by toxic exposures, workers injured on the job, and consumers harmed by defective products and unsafe medical devices.

Our approach combines legal strategy with scientific insight. We collaborate closely with leading medical and public health experts, including epidemiologists, toxicologists and occupational health specialists, to investigate the root causes of injuries and illnesses and build strong, evidence-based cases. These partnerships allow us to tackle complex litigation with the depth and precision it demands.

Supported by a dedicated team of legal professionals and strategic alliances with respected firms nationwide, we work tirelessly to protect our clients’ rights and pursue meaningful results. At Thornton Law Firm LLP, our mission is simple: to help those harmed by negligence or unsafe practices seek justice and move forward with confidence.
