Talia Nissimyan is a senior associate at Kaplan Hecker & Fink LLP. She specializes in complex civil litigation, and her practice also spans enforcement matters, investigations, and the firm’s public service work. Talia joined Kaplan Hecker from Ropes & Gray LLP, where her practice also included a range of privacy & data security matters and advising financial institutions.

At Kaplan Hecker, Talia advises clients on high-stakes issues when their reputations and purpose are on the line, regardless of the forum, posture, or area of law at issue. She was a lead associate in the firm’s defense of Amber Heard against Johnny Depp’s $50 million defamation lawsuit, developing the evidence against Depp and notching critical wins in defending Heard’s right to speak out about her experiences with sexual violence. She played a key role representing Kentucky Governor Andy Beshear before the United States Supreme Court, defending the constitutionality of his COVID-19 policies and securing a 7-2 opinion in his favor. Talia represented Gigi Hadid in a federal copyright suit hailed as making novel points about the fundamental unfairness of a woefully outdated doctrine. She is a part of the Kaplan Hecker team representing Elysium Health in simultaneous commercial disputes with a single competitor in federal court in both New York and California. Talia regularly advises clients regarding complex #MeToo matters with sensitive publicity elements, whether plaintiffs, defendants, or pre-litigation, including high-profile individual clients and a leading American civil-rights organization. With Kaplan Hecker partner Joshua Matz, she represented a leading group of Establishment Clause scholars in five federal courts, including the United States Supreme Court, in their bid to resist Trump administration efforts to limit contraceptive coverage. (Though the Supreme Court decided in President Trump’s favor, Justice Ginsburg’s final dissent quoted their brief directly.) Talia practices in state trial and appellate courts, federal trial and appellate courts, and before government agencies. She regularly counsels clients through investigations, civil discovery, to trial, and on appeal. She was named a Super Lawyers "Rising Star" in 2020 and 2021, and a Leadership Council on Legal Diversity "Pathfinder" in 2020.  

In her pro bono practice, Talia regularly represents LGBT clients facing steep odds in obtaining agency relief. Together with her co-counsel at Ropes & Gray, Talia secured asylum for her client facing persecution in his native Columbia despite the Trump administration’s efforts to curtain the availability of asylum to clients like hers. With the same team, Talia secured a discharge upgrade for a client discharged from the Navy for homosexuality, as well as service-connected VA benefits for the sexual trauma her client suffered during service and the client’s associated PTSD. Talia has extensive experience advising trans clients on updating their name and gender markers to conform with their identities. 

Talia clerked for the Honorable Robert W. Sweet of the Southern District of New York. She received her law degree from the University of California, Berkeley, School of Law, where she served as Senior Book Reviews & Essays Editor of the California Law Review, and worked at Human Rights Watch in its Terrorism/Counterterrorism Department where she contributed to the organization's national security reporting. Talia holds a master’s degree with honors from the University of Chicago’s Committee on International Relations, and a bachelor’s degree from the University of California, Berkeley.
