Sergio Oehninger represents companies in complex insurance coverage and bad-faith disputes in the United States and around the world. He counsels multinational corporations on insurance coverage and risk management issues arising in various industries, including retail, energy, aviation, financial services, construction, hospitality, and real estate. He also serves as co-leader of the firm’s Hispanic/Latino Lawyer Network and co-chair of the Juncadella Corporate Counsel Group.
Sergio’s advice focuses on risks such as cyber and data breaches; commercial general liability (CGL); products and environmental risks; directors and officers (D&O) liability; property and casualty; business interruption; supply chain disruptions; war, nationalization, and political risks; trade credit exposures; aviation and marine hull and cargo risks; excess, umbrella, and integrated risks; specialized insured and reinsured risks under occurrence based or claims-made policies, including pooled risks managed by managing general agents or underwriters; and surety bond risks.
As part of his Latin America practice, Sergio advises corporate clients on cross-border exposures and risk transfer in connection with transactions, supply chain logistics, projects, operations, products, and services. He serves as co-chair of the Juncadella Corporate Counsel Group (JCCG), an informal organization of more than 300 South Florida–based in-house counsel who primarily advise companies with business interests in Latin America and the Caribbean.
Sergio’s litigation, arbitration, and counseling experience includes insurance coverage and bad-faith matters involving billions of dollars in cumulative losses or exposures. He has handled matters before federal and state courts throughout the United States and alternative dispute resolution tribunals, including the American Arbitration Association (AAA), the AIDA Reinsurance and Insurance Arbitration Society (ARIAS-US), and the Society of Maritime Arbitrators.
A strong advocate of public service, Sergio has served on the boards of several nonprofits. His pro bono work includes advice to a 501(c)(3) charity dedicated to combating gang violence and raising funds benefitting children living in poverty, appellate work on behalf a nonprofit that advocates for immigrant survivors of violence, and insurance coverage advice and litigation for a not-for-profit entity that was the target of a social engineering and funds transfer fraud scheme involving millions in stolen funds.
