Since returning to private practice, she has been at the forefront of some of the most closely watched cases in the country. Her recent representations include advising:

During her 11 years at the SDNY, Ms. Griswold held some of the Office’s most senior leadership roles. As deputy U.S. attorney and chief counsel to the U.S. attorney, she oversaw the work of more than 400 prosecutors and staff, supervised every criminal and civil investigation in the district and coordinated with senior DOJ leadership and law enforcement agencies nationwide. She also managed the SDNY’s media strategy and served as the final decision-maker on case recommendations. The U.S. attorney described Ms. Griswold as “a generational talent” and “a relentless investigator, a talented trial lawyer, and a strategic counselor and leader with excellent judgement” in a press release announcing her departure from the SDNY in 2024.

As chief of the Securities and Commodities Fraud Unit, Ms. Griswold supervised dozens of high-profile corporate and individual investigations, including matters involving hedge funds, private equity firms, accounting fraud, valuation disputes and market manipulation. She also personally tried a series of complex fraud cases to verdict and coordinated closely with the SEC, CFTC and FINRA, including on cross-border enforcement actions.

Additionally, Ms. Griswold founded and co-chaired the SDNY’s Committee on Artificial Intelligence and Committee on Technology and Electronic Evidence. She is a frequent speaker on issues related to individual and corporate prosecutions, private funds and women in leadership.

Prior to joining the SDNY, Ms. Griswold worked for five years as a white collar litigator at a global law firm. She tried three cases to verdict during this time, including two federal criminal trials, one of which ended in a hung jury and the other with an acquittal on the top charge. The civil trial resulted in a jury verdict in favor of her client.

In recognition of her work, Ms. Griswold is ranked by Chambers USA and has been honored by City & State New York as part of its 2025 Law Power 100, in addition to being named one of Lawdragon ’s 500 Leading Global Litigators, 500 Leading Litigators in America and 500 Global Leaders in Crisis Management.
