Michael’s practice focuses primarily on insurance coverage litigation and insurance counseling in matters ranging from large, complex litigation to discrete, focused disputes. Specifically, Michael has experience representing and advising domestic and international insurers in non-litigated and litigated matters in both state and federal courts involving general liability insurance, property, environmental, excess liability claims, professional liability, and directors and officers insurance. 

Michael has also maintained a defense practice which works directly with business owners and individuals to assist in litigation including personal injury, product liability, and construction litigation. Michael handles matters in the Appellate Courts of New Jersey and has successfully argued on numerous occasions before the New Jersey Appellate Division. In addition to formal litigation, Michael has experience in arbitration and mediation and has provided coverage advice to clients to assist them in avoiding disputes without the need for litigation.

More recently, Michael has been working with a team at Coughlin Duffy LLP as lead counsel for insurers in multiple insurance coverage disputes relating to contamination of Lower Passaic River. Michael previously was heavily involved with teams at Coughlin Duffy LLP who successfully litigated a number of complex multi-jurisdictional coverage disputes related to data breach and cyber theft.
