Bobby’s primary practice is counseling international and domestic maritime industry clients like owners, operators, and charterers of vessels and their insurers.

He was also lead maritime counsel to one of the world’s largest marine fuel traders in its bankruptcy proceedings and related litigation during which he appeared in federal courts throughout the United States, several foreign courts and arbitration tribunals, and the United States Supreme Court.

He provides pro bono legal assistance to mariners during suspension and revocation proceedings before the United States Coast Guard. He was pro bono general counsel to the American Caribbean Maritime Foundation.
As a general commercial litigator and advisor, Bobby has handled a variety of contract and license disputes, enforced arbitration awards and foreign judgments, represented creditors in bankruptcy proceedings, defended complex civil RICO claims, acted as local counsel in New York federal courts, taken discovery in the US in aid of foreign proceedings under 28 U.S.C. § 1782, given expert opinions on US and New York law in support of foreign litigation, and counseled businesses on many general matters such as the formation of corporations and partnerships, negotiation of agreements, and drafting of standard terms and conditions.

Bobby earned his J.D. degree from St. John's University School of Law, where he served as president of the Joseph A.
