[email protected]



Marc is an esteemed litigator with over two decades of experience guiding insurers, reinsurers and brokers through high value, high stakes litigations and arbitrations. Marc is equally skilled at representing insurance and reinsurance clients in court and before US and international arbitration panels. He has successfully taken dozens of matters to trial and has resolved many more on favorable terms through motion practice or settlement. Because of Marc’s unique blend of expertise - which combines a deep proficiency in the (re)insurance business with the intricacies of courtroom and arbitration practice - clients frequently turn to Marc to guide them through their most challenging disputes. As he is able to get up to speed quickly given his facility with a diverse range of insurance and reinsurance products, Marc is frequently called on to step in and take over trial proceedings or to provide a second look when clients need a fresh strategy to resolve a matter favorably.

Marc is committed to finding efficient and practical solutions for clients in pressurized situations and is highly focused on project management and cost predictability, to meet the business objectives of each client and on each project. For over a decade, Chambers USA has recognized Marc as a leading attorney in insurance and reinsurance dispute resolution, with clients praising his “tremendous expertise and a working knowledge of reinsurance law," his versatility in handling “any kind of case," and noting that he is “creative in finding solutions, very good in court and very practical” while taking a “very, very client-centered approach to reinsurance law.”

Marc is also deeply involved with ARIAS US - the premier US organization dedicated to enhancing insurance and reinsurance arbitrations for US and international clients - and currently serves as its President, where he and other industry leaders are responsible for developing and enhancing arbitration products and defining the philosophical direction of the organization. Marc also co-chairs other ARIAS US Committees including the Education Committee (which he has co-chaired since 2015), and the Strategic Planning Committee. He also serves as the Co-Chair of the New York State Bar Association’s International Insurance and Reinsurance Committee.

Prior to joining Mintz, Marc worked at two boutique firms as well as an international firm specializing in insurance and reinsurance disputes.
