Biography

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

While in law school, Dennis served as 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.
