Robert Goldhaber

Robert Goldhaber is an accomplished attorney specializing in commercial collections and judgment enforcement. As managing partner and attorney at Rosenthal & Goldhaber, P.C., Robert has dedicated his career to helping businesses that are owed money – but have not yet received payment – for goods or services they provided.

In 1991, Robert joined his father Richard and his grandfather Max in the law practice of Rosenthal & Goldhaber, which is now a third-generation law firm. Robert’s grandfather Max Goldhaber founded the firm in 1940 with partner Benjamin Rosenthal, and the firm became one of Long Island’s most respected law firms. 

As Robert looked up to his father and grandfather for guidance and inspiration, it seemed logical to him that he would become an attorney. A graduate of Brandeis University, Robert earned his bachelor’s degree in economics in 1988. After graduation, he went on to earn his law degree from the Boston University School of Law. Robert is currently admitted to practice law in the state courts of New York and Massachusetts, as well as the southern and eastern New York Federal Districts.

Throughout his career, Robert has litigated many high-profile cases, including one case that created a new legal exception to a well-settled area of law involving signatures on personal guarantees.

Today, Robert manages the day-to-day operations of Rosenthal & Goldhaber, and he is also a practicing attorney. He is proud to continue the firm’s legacy of dedication, commitment, and passion for helping all clients of the firm. Robert believes that a rare approach – including a mixture of kindness, fairness, aggressiveness, and persistence – has been key to the firm’s long-term success.

In addition to Rosenthal & Goldhaber, Robert is also President of Corporate Substance Abuse Programs, Inc., a leader in customized corporate drug-testing programs.

As a Long Island native and resident of South Setauket, NY, Robert takes pride in giving back to his community. He is a member of many organizations that help promote the economic welfare of the community.

Robert is also a member of the UJA-Federation of New York, where he serves on the committee for the Long Island Building Materials Division. Additionally, as a member of Temple Isaiah Brotherhood (based in Stony Brook, NY), he participates in charitable activities to support his community.

Whenever he can, Robert enjoys spending time with his wife and three children. The time requirements of managing a law practice and running a drug-testing company make leisure activities precious. Robert’s outside interests include playing tennis and golf, and he is also a connoisseur of fine wines.
