About William L.
William L. Pierog combines a technical undergraduate background and formal legal training in technology law. He earned a B.S. in Cognitive Science from the University of California, San Diego in 2007. Five years later he completed his J.D. at the University of California, Berkeley School of Law and also received a Certificate in Law & Technology in 2012. Those academic credentials shape the questions he raises about how law interacts with emerging systems and products.
He entered private practice after law school. His resume includes time at Fenwick & West LLP, a firm known for handling legal work for technology companies. At Fenwick he worked on matters that required both an understanding of legal doctrine and an appreciation for technical detail. Colleagues and clients have relied on his ability to translate complex technical topics into clear legal analysis.
Pierog is licensed to practice in California. His education and early work experience point toward legal work that touches on technology-driven business, though his record covers a range of matters typical for attorneys in technology-focused practices. He brings the analytical tools of cognitive science to tasks such as reviewing technical contracts, assessing regulatory questions, and advising on transactional issues.
His training at Berkeley Law emphasized issues at the intersection of law and technology. The certificate program there exposed him to intellectual property, privacy, and regulatory concerns that are common in Silicon Valley and the broader technology sector. That background informs how he evaluates risk and frames legal options for clients who operate or invest in technical products and services.
In practice he balances legal research, drafting, and client counseling. He has advised on contract negotiation, compliance questions, and internal policy reviews. He also participates in internal firm efforts to align legal strategy with product development timelines when clients are rolling out new offerings. His work requires steady attention to detail and an ability to communicate technical and legal concepts to nonlawyers.
As of 2026 he continues to practice in California and is associated with Fenwick & West LLP. He maintains a practice that addresses legal issues arising where technology and business intersect.
