Robert Goldhaber

Robert GoldhaberRobert is an accomplished attorney specializing in business and commercial law, including collections law, business planning and management and commercial litigation. He serves as managing partner of a third-generation law firm, Rosenthal & Goldhaber, P.C., one of Long Island’s most respected, which was founded by his grandfather Max Goldhaber and partner Benjamin Rosenthal in 1940.

As Robert looked up to his father for guidance and inspiration, it seemed logical to him that he would become an attorney. A graduate of Brandeis University, he 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.

In 1991, Robert joined his father Richard and grandfather Max in the law practice of Rosenthal & Goldhaber, P.C. To this day, Robert still embodies the dedication, commitment and passion for the clients of Rosenthal & Goldhaber P.C. that both his grandfather did in 1940 and his father did when he joined the practice in 1961. During his career at the firm, Robert has litigated many high-profile cases, including one which 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 P.C. He is also President of Corporate Substance Abuse Programs, Inc., a leader in customized corporate drug-testing programs.

A Long Island native, Robert takes pride in giving back to the communities in which he serves. He is a member of many organizations which help promote the economic welfare of our community such as Advancement for Commerce Industry and Technology (ACIT), the Suffolk County Bar Association, the Nassau County Bar Association as well as the Commercial Law League of America (CLLA).

Robert is a member of the UJA-Federation of New York where he serves as a committee member for the Long Island Building Materials Division. As an active member of the Temple Isaiah Brotherhood, he is a participant in charitable activities that support his community.

A resident of South Setauket, NY, 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 a connoisseur of fine wines.
