As the Managing Partner of the San Francisco office, I have the privilege and opportunity to see our teams in daily action – and I am unfailingly impressed.

Philip is the Managing Partner of the San Francisco office and a partner in our Securities Litigation, Enforcement, and White-Collar Defense Group. Philip is a problem solver and go-to advisor for companies and their directors and officers in the areas of securities class actions, shareholder derivative suits, and regulator inquiries and investigations. He has a long track record of securing successful outcomes, including winning at trial, winning at the pleading stage and on summary judgment, and prevailing on appeal.  

Philip’s clients represent a broad range of industries including computer hardware, consumer products, energy, financial services, gaming, technology, and telecommunications. He has successfully defended dozens of firms and individuals including Zynga, Oracle, Infineon and notably, JDSU and its former executives where he contributed to the complete defense verdict in a securities class action jury trial seeking $20 billion in damages for alleged securities fraud and insider trading.

In addition to his practice, Philip serves as Chair of the Risk Management Committee and Deputy General Counsel to the Firm, setting the strategic direction on risk management issues.

Philip is admitted to practice in the United States District Courts for the Central, Eastern, Northern, and Southern Districts of California; and the United States Courts of Appeals for the Ninth and Federal Circuits.

Philip is the immediate past Chair of the board of the San Francisco AIDS Foundation, a nonprofit organization founded in 1982 to provide education and treatment.
