Derek Wallen

Derek has been practicing business law for nearly 20 years. He represents a wide variety of corporate and individual clients in both litigation and transactional matters. He has practiced in Los Angeles for 10 years and in addition has practiced in New York City, Chicago and Silicon Valley. Eight years of his career was spent at O’Melveny & Myers, a leading global law firm.

Derek represents both plaintiffs and defendants in a broad array of complex commercial disputes, including corporate, securities and employment-related litigation. He frequently litigates in both state and federal court and in ADR (alternative dispute resolution) settings. He is admitted before every federal district court in California and the U.S. Court of Appeals for the Ninth Circuit. He believes in litigating aggressively but ethically and in helping the firm’s litigation clients clearly define their objectives at the outset of a case so that those objectives can be met in the most efficient manner possible.

Derek also has deep experience in securities and financing transactions, mergers and acquisitions and corporate governance matters. In his transactional practice he has represented Fortune 100 companies, private equity firms, development stage start-ups, entrepreneurs and major investment banks. He has closed tens of billions of dollars’ worth of securities, financing and M&A deals, and he has worked on some of the most innovative IPOs and Wall Street debt transactions of the last 15 years. He often serves as outside general counsel to companies in need of sound general oversight of their legal affairs.

In 2018, Derek was given the Hon. Benjamin Aranda III Outstanding Public Service Award by the Los Angeles County Bar Association for his years of pro bono work on behalf of domestic violence and elder abuse victims.

Derek received his Bachelor of Arts degree from UCLA and his law degree from Stanford Law School, where he was selected to join the Order of the Coif. Derek is a member of the California bar.
