A former DOJ trial lawyer and Washington State Assistant Attorney General, Zach helps public and private clients navigate all phases of civil litigation.

Zach is an experienced trial and appellate lawyer who helps his clients navigate all stages of civil litigation, internal and government investigations, and novel challenges at the intersection of law, policy, and politics. A former U.S. Department of Justice trial attorney and Washington State assistant attorney general, Zach brings strategic insight and a broad range of experience to his work for public, private, political, and nonprofit clients. Zach has become one of Washington’s leaders in defending state and local governments against legal challenges to emergency public health measures adopted during the COVID-19 pandemic. In over 50 such cases, no challenger has won any form of relief against Zach’s clients. He is also one of the Pacific Northwest’s most experienced legal advocates supporting firearm safety measures, representing the region’s leading gun violence prevention nonprofits to defend common-sense firearm laws in Washington and Oregon—including restrictions on assault weapons and large-capacity magazines. In eight federal and state court lawsuits brought by the gun lobby, Zach’s clients are undefeated.

After a federal appellate clerkship, Zach joined an international law firm based in Seattle. With a diverse client base ranging from Fortune 100 companies to small nonprofits, Zach became an adaptive civil generalist and courtroom advocate, litigating across a wide range of subject matter and taking seven cases to trial. In the U.S. Department of Justice’s Civil Rights Division, Zach litigated voting rights cases on behalf of the federal government, successfully suing to invalidate Texas’s strict voter ID law under the Voting Rights Act. In the Washington State Attorney General’s Office, Zach represented the State in cases against the Trump administration, including challenges to its deregulation of 3D-printed firearms and to the “public charge” immigration rule. Zach also led the litigation team defending the State’s emergency response to COVID-19, going undefeated in dozens of lawsuits.

Before going to law school, Zach taught global history at a Brooklyn high school through Teach For America. Born and raised in Seattle, Zach is a proud graduate of Garfield High School, where he played baseball and in the jazz band. He continues to play sax and piano in his free time, and also enjoys cycling, yoga, and live music.

Zach serves on the boards of Northwest Justice Project and the Washington Bus. He is a Commissioner on (and former Chair of) the Seattle Ethics and Elections Commission.
