Stephen Marcellino is a seasoned litigator and strategic advisor who focuses on general, product and professional liability defense and insurance and reinsurance coverage matters. Steve has been with the firm since its inception. As the co-chair of Wilson Elser’s General Liability & Casualty practice, chair of the firm’s ADR practice and long-standing member of the firm’s Executive Committee, Steve has been recognized as one of the most influential and well-regarded lawyers in the United States serving the insurance community.

During the last 40 years, Steve has handled some of the firm’s most complex, high-exposure litigations and arbitrations as a trial lawyer and manager of national and international cases. He has designed and implemented innovative alternative dispute resolution programs, bringing contentious multi-plaintiff and claim portfolios matters to expeditious and cost-effective conclusions. In addition, he acts as a neutral mediator on behalf of the U.S. federal court system in connection with high-profile matters.

With his knowledge and experience as a backdrop, Steve regularly is retained to serve as settlement counsel to carriers and their insureds in connection with nationwide class actions, multi district litigations, employment practices, catastrophic multiparty injury and property damage cases, domestic and international product liability claims, and other complex issues. In this role, he assesses, develops and implements a settlement strategy for a case designed to effectuate a resolution short of trial through negotiation and mediation. He also regularly is engaged by insurance company clients to resolve coverage disputes and provide strategic advice in connection with product development and program creation.

He is regularly retained to assist our clients in their Enterprise Risk Management process. He evaluates emerging risks and provides strategic advice in connection with product development and program creation.

Professional Activities
Steve is a sought-after speaker in his areas of concentration and frequently gives lectures in the United States, London and throughout Europe for various state and national associations, professional organizations and universities, and the insurance industry. He has presented seminars on risk management, loss prevention, dispute resolution, litigation management, catastrophic response and insurance. Steve also has written and contributed to a number of articles and books, including one of the leading books in England on the topic of alternative dispute resolution.

At a time when professional liability insurance became difficult for many to attain, Steve helped form the Professional Liability Underwriting Society (PLUS) to help insurers meet the needs of professionals across the United States. He also was involved in developing the Registered Professional Liability Underwriter (RPLU) designation and has served as general counsel to this program. In 1998, he received the Founder’s Award from PLUS in recognition of his contribution to the industry.
