Sean Mahoney is a trusted advisor to insurers and commercial clients who is respected for his knowledge, responsiveness, creativity and diligence. He has extensive and successful trial and litigation experience in state and federal courts as well as in numerous private arbitrations involving complex insurance coverage, life insurance, reinsurance, business torts, and commercial contract disputes. 

Sean's insurance practice spans a broad range of complex insurance coverage matters. He routinely evaluates coverage and advises third-party primary and excess liability insurers and has frequently and successfully litigated liability insurance coverage disputes in court and in private arbitration. Sean also frequently advises life insurers with respect to life insurance policies and litigates disputes over life insurance claims. Sean’s diverse insurance coverage practice has also included litigating commercial property insurance coverage issues and transnational reinsurance coverage disputes. 

Sean has also successfully litigated numerous commercial contract disputes both within and without the insurance industry. Within the insurance industry, commercial insurers have frequently called upon him to oversee and litigate disputes involving the collection of premiums, managing general agents, retail agents, insurance producers, and third-party claims administrators. Outside of the insurance industry, Sean has also counseled clients and handled litigation over sale-of-goods and service contracts, surety agreements, and the collection and enforcement of judgments. 

Since Sean is a problem-solver, clients often seek his advice and counseling with respect to insurance coverage and commercial matters outside of the litigation context. He has frequently negotiated favorable resolutions for insurers and other clients involved in disputes with third parties that have avoided costly and protracted litigation.

While in law school, Sean served as an Editor of the Villanova Environmental Law Journal and as a Board Member of the Public Interest Fellowship Program at Villanova Law School. Upon graduation, Sean served as judicial law clerk in the United States Court of Appeals for the Third Circuit before entering private practice in 2004.
