I think being able to see things from different perspectives is incredibly important.

With her one-of-a-kind skillset, Jina Choi represents public and pre-IPO companies, financial institutions, asset management firms, boards of directors, audit and special committees, and individuals in internal investigations, U.S. Securities and Exchange Commission (SEC) and other government investigations, enforcement-related litigation, as well as compliance-related issues. Jina joined the firm after over 16 years with the SEC, where she ultimately served as Director of the San Francisco Regional Office, helping to enforce many of the laws that govern the public and pre-IPO companies she now represents.

Many of Jina’s achievements as an SEC enforcement lawyer and federal prosecutor are public record, and her former colleagues and senior officials at the SEC describe her as “an exceptional attorney” who has shown “leadership and [a] thoughtful approach to new and complex issues” and “strategic thinking on examination initiatives, particularly those involving developing technology.” She is praised for leading the San Francisco office of the SEC in bringing “a series of ground-breaking enforcement actions, including against public and private technology companies in Silicon Valley and their senior officers” and “establish[ing] important precedents” that will continue to be followed in the years ahead.

Jina has experience in matters related to financial reporting and accounting, disclosure, insider trading, offering fraud, investment adviser and broker dealer fraud, auditor misconduct, market structure, and the Foreign Corrupt Practices Act (FCPA). As Regional Director of the SEC’s San Francisco Office, she led a staff of over 130 attorneys, accountants, and professionals and worked closely with leadership in numerous U.S. Attorney’s Offices, the Department of Justice (DOJ), the Financial Industry Regulatory Authority (FINRA), the Public Company Accounting Oversight Board (PCAOB), the Commodity Futures Trading Commission (CFTC), and state securities regulators in California, Oregon, Washington, Idaho, and Alaska, as well as the UK’s Financial Conduct Authority. She also provided training to attorneys and accountants from the Hong Kong Securities and Futures Commission and the China Securities Regulatory Commission.

In addition to her time at the SEC, Jina’s distinguished government experience includes serving as an Assistant U.S. Attorney in the Northern District of Texas, serving as a trial attorney in the Civil Rights Division of the DOJ, and serving as a law clerk for the Honorable Robert P. Patterson, Jr., in the U.S. District Court, Southern District of New York. She also has experience in private practice at other large law firms.

  • Asian Americans Advancing Justice – Asian Law Caucus, Board of Directors
  • SEC Historical Society, Board of Advisors
  • Women In Securities (WISe) Steering Committee
