Brian E. O'Donnell


Brian E. O’Donnell is Co-Chairman of Riker Danzig and Co-Chair of the Firm’s Insurance and Reinsurance Group.
He has successfully resolved a variety of complex matters, including high-stakes reinsurance and insurance coverage disputes, class action products liability lawsuits, and government investigations of insurance and financial regulatory matters.

Brian is a seasoned litigator whose expertise in handling complex commercial matters makes him counsel of choice for clients seeking effective solutions to significant legal problems.

Such matters typically involve a daunting level of technical detail, complex legal issues, and material exposure. But when Brian takes on one of these cases, he strives to cut through the minutiae and focus the matter on the core issues that best support his client’s interests. He has found that using the evidence to tell his client’s story in a succinct, straightforward manner is the only way to be successful in such matters.

Brian’s reputation for effectively handling such complex commercial matters is evidenced by the top AV rating given to him by the peer-reviewed Martindale-Hubbell lawyer directory. It is a reputation that extends internationally, with clients based throughout the United States, the United Kingdom, and Bermuda. He has successfully represented clients in many significant, multimillion-dollar litigations.
