Early Life and Education

She then attended Yale Law School, earning her Juris Doctor in 2011. During her time at Yale, she distinguished herself as a finalist and co-director of the Barristers’ Union.
Early Career and Clerkships
Following law school, Sassoon gained valuable experience through clerkships with prominent judges. From July 2012 to August 2013, she served as a law clerk for Judge J. United States Court of Appeals for the Fourth Circuit’s Harvie Wilkinson III. She then clerked for the late Justice Antonin Scalia of the U.S. Supreme Court from July 2012 to August 2013. She considered Scalia “my kind of feminist,” noting that he pushed her to engage rigorously with her work and even taught her how to handle firearms, fostering resilience that she found essential for navigating a male-dominated profession.
Career as a Prosecutor
Sassoon began her career as an Assistant United States Attorney in the SDNY in 2016. She quickly made a name for herself by prosecuting complex cases of violent crime and securities fraud. She tried murder and racketeering cases while working in the Violent and Organized Crime Unit.

Her rigorous four-hour cross-examination of Bankman-Fried was praised for highlighting discrepancies between his public statements and private behavior, ultimately leading to his conviction and a 25-year prison sentence. She was also involved in the prosecution of Lawrence V. Ray for extortion and sex trafficking related to his exploitation of Sarah Lawrence College students, resulting in a 60-year prison sentence.
Her work as a prosecutor earned her several accolades, including the FBI Director’s Award for Outstanding Criminal Investigation in 2024 and the Women in Federal Law Enforcement Top Prosecutor Award in 2023.
