He has successfully represented clients in the US Supreme Court and the California Supreme Court, as well as federal and state appellate courts nationwide. Gonzalo works with clients and trial counsel to reverse trial court error, defend hard-fought victories, and help shape the law. As an appellate lawyer, he brings a fresh perspective, and rigorous analysis and writing designed to persuade courts to rule in his clients’ favor. He has spoken on national and statewide panels regarding effective amicus advocacy.

Litigation and Trial Strategy
Gonzalo has advised trial counsel on strategic trial issues (experts, jury instructions, preserving issues for appeal), and prepared significant pre- and post-trial briefs (motions to dismiss, anti-SLAPP, summary judgment, directed verdict, new trial). He has also prepared writ petitions seeking immediate appellate review of adverse orders that are not directly appealable.
Gonzalo’s experience as a government lawyer involved advising and representing the State of California, its agencies, and its officers in the most sensitive and complex matters, often against the federal government. That experience informs his approach to trial and appellate litigation involving public entities or issues that may prompt interest from government regulators.
Previously, Gonzalo served as the Federal Judicial Clerk to the Honorable Maxine M. Chesney, Senior Judge, Northern District of California, and to the Honorable Anthony W. Ishii, Chief Judge, Eastern District of California.
