Meet Zach

Zach is a shareholder on the firm’s Litigation, Data Privacy & Cybersecurity, and Technology & Digital Business teams. He chairs the Data and Technology Disputes practice group and is a member of the firm’s recruiting and ethics committees.

No business wants to deal with a cybersecurity breach or a complex technology dispute. But the reality is that it’s often unavoidable. Disputes are inevitable and have grown exponentially more common and complex as businesses integrate new technologies. And the prevailing attitude about the risk of a security incident is, quite simply, “not if, but when.”

Zach helps clients through these difficult—often crisis—situations with a steady hand, a depth of substantive and procedural knowledge, and a big-picture focus on getting to the best outcome. He’s successfully guided clients through active security breaches, post-breach notification, resulting disputes, and ultimately to business recovery. Zach’s litigation experience includes trial- and appeals-level work on high-stakes cases as varied as consumer class actions, prisoner civil rights claims, and complex business torts. He particularly enjoys working on cases involving the complex issues surrounding technology and data.

Zach earned a certificate in cybersecurity from UCLA and is Certified in Cybersecurity (CC) by the International Information System Security Certification Consortium (ISC)2. He also holds the Certified Information Privacy Professional/US (CIPP/US) and Certified Information Privacy Manager (CIPM) certifications from the International Association of Privacy Professionals (IAPP). Zach was selected to and served on Sedona Conference Working Group 11’s drafting group on the legality of ransomware payments under U.S. law.

Before joining Godfrey & Kahn, Zach spent nearly a half-decade clerking for U.S. District Judge J.P. Stadtmueller of the Eastern District of Wisconsin.

Outside of work, Zach enjoys distance long-distance running and listening to and writing music. He is a former member and songwriter of several touring bands.
