Biography

A trial lawyer, Dennis Costigan litigates for patients who are suffering from the painful, life-altering injuries associated with allegedly faulty medical devices, working to hold accountable those responsible for inadequate product testing, research and warning.

Dennis litigates for patients harmed by defective hernia mesh, including engaging in discovery, expert, trial, and settlement work. In 2022, Dennis was member of the trial team that secured a $4.8 million verdict* against Davol, Inc. and C.R. Bard in Rhode Island state court. Previously, he helped litigate and resolve thousands of claims brought by women harmed by defective transvaginal mesh.

Outside of his medical device work, Dennis also assists the residents of East Palestine in their ligation against Norfolk Southern stemming from a Feb. 3, 2023 train derailment and toxic chemical spill.

While in law school, Dennis was a legal intern with the Rhode Island Department of Health and Human Services performing detailed discovery and research into departmental legislation, including Medicare bankruptcy claims research. He also acquired research and writing experience as an intern at a Rhode Island law firm and as a law clerk for Motley Rice.

Dennis draws from a history of involvement in federal, state and local election campaigns, and was acknowledged with a CALI Excellence for the Future award in Judicial Behavior and Social Change during law school.
