As the Head of Gunderson Dettmer’s Data Privacy Practice, Anna counsels clients on a broad range of U.S. and European data privacy and security issues, including the California Consumer Privacy Act (CCPA), the General Data Protection Regulation (GDPR), HIPAA, COPPA and complex cross-jurisdictional data privacy matters. Anna represents emerging company clients across industry sectors, from consumer internet, consumer products, ad tech, health tech, consumer genetic, financial technology, and software and SaaS industries, as well as a number of leading venture capital firms. Anna has significant experience guiding clients through GDPR and CCPA compliance, and advising on model contract clauses, privacy policies, data processing agreements, and global privacy compliance strategies. She also advises on data privacy and security issues in venture capital financings, mergers and acquisitions, and IPOs.

The FIP and CIPP designations are the global standard in privacy certification, and demonstrate a strong foundation in U.S. and EU private-sector privacy laws and regulations.
