Knowledgeably steering clients through complex and emerging issues relating to data privacy, information security, and consumer protection, Joe is a Certified Information Privacy Professional (CIPP/US) who began his career at MoFo as a privacy class action litigator. Joe has represented major retailers and technology companies in U.S. federal and state actions involving alleged violations of consumer protection and privacy laws, and is well versed in U.S. federal and state, and international data protection laws such as the CCPA, GDPR, HIPAA, and CFAA. 

Joe has helped clients respond to multijurisdictional data security incidents, including by developing breach notifications both in the U.S. and around the globe.  He has advised clients on matters directly involving the Federal Trade Commission, the U.S. Department of Health and Human Services Office for Civil Rights, state attorneys general, and numerous foreign regulators, including the UK Information Commissioner’s Office. 

A seasoned and tech-fluent incident responder, Joe has worked for clients on dozens of complex security incidents, including data breaches, ransomware attacks, and insider sabotage, while collaborating closely with leading cybersecurity professionals and e-discovery vendors. Joe has drafted and run engaging and tailored cybersecurity tabletops for numerous Fortune 500 clients, designed to test cyber-readiness from the helpdesk level to the C-suite. Additionally, he often works with in-house legal and security teams to oversee red-team exercises and security assessments, while carefully balancing privilege issues.

Joe has extensive experience in health care privacy, which also happens to be an area of personal passion. He has assisted numerous clients in developing their HIPAA privacy and security programs, carrying out enterprise risk assessments, and responding to potential breaches involving protected health information. Joe also frequently counsels clients on the privacy and data security risks involved in merger-and-acquisition deals, as well as during the negotiation of service agreements involving the processing of personal data.
