Alexander Klein is the head of Barket Epstein’s commercial litigation unit and a co-chair of its division on Civil Rights. He joined the firm in 2013 after having worked for the Bank of New York Mellon and Merrill Lynch, as well as on the floor of the New York Stock Exchange. Since joining the firm, Mr. Klein has helped grow the civil litigation practice exponentially.

In the commercial sphere, he has represented and won cases for companies of all sizes, from growing local businesses to international publicly traded corporations. He has won cases that clients and prior lawyers labeled “impossible,” and won decisions that changed the law in a variety of his clients’ respective industries. To that end, Mr. Klein has achieved breakthroughs in legal arenas including ways to attack ADR provisions in commercial contracts, the rights of accused students in Title IX proceedings, the rights of defaulting borrowers in high stakes debtor-creditor disputes, employee work-rights in the face of overly restrictive “trade secret” agreements, and the ability of auto body shops to obtain fair labor rates using New York’s Lien Law—among other topics.

In addition to his commercial practice, Mr. Klein has been a driving force in Barket Epstein’s renowned division on civil rights. In that capacity, he has contributed to several newsworthy matters, including the record-breaking wrongful conviction settlements on behalf of Samuel Brownridge, and Christopher Loeb’s civil action that helped lead to the imprisonment of Suffolk County’s District Attorney and Chief of Police. He has also represented clients in a vast array of other civil rights matters, recovering millions of dollars on behalf of victims of law enforcement abuse.

For his work, Mr. Klein has been recognized by Super Lawyers as a “Rising Star.”
