About J. Mia Tsui

Mia advises companies and their officers and directors with cutting edge issues of corporate law and federal securities law.  Recently, she has represented electric car manufacturers and leading technology companies in high-profile federal securities class actions, corporate transactions, and shareholder relations. 

Mia’s focus on complex transactions began with her transactional and corporate experience earlier in her career.  Her expertise includes mergers and corporate governance matters, and she has worked on multiple U.S. and cross-border public-to-private and public-to-public transactions as both Corporate M&A and Corporate Finance counsel. In addition to advising targets on auction processes and a private equity investment entity in its combined debt and equity financing of a biotech start-up, she has also advised on complex litigation and class action settlements.  Mia also represents pro bono clients, including in a class action against the U.S. government in the District of Columbia and D.C. Circuit, as well as on an amicus brief involving the same defendants in the Ninth Circuit.  

Mia received her J.D. from the University of California, Berkeley School of Law and her A.B. from Princeton University, where she majored in music.  For nearly a decade prior to law school, Mia worked as a consultant and director of soccer and educational organizations, running a national soccer program in both its Boston and San Francisco branches, and training and managing teams of 12-30 public school educators.
