Zach has spent more than twenty years in federal and state courts and in arbitration. He has represented clients in diverse industries including entertainment, professional services, financial services, marketing, and manufacturing. As a partner at Nelson Hardiman, Zach leverages his broad knowledge of industries and business models to advise healthcare clients.

Focused on Litigation Solutions Across a Broad Spectrum of Providers and Issues

Zach regularly represents healthcare clients in cases involving breach of contract, fraud, unfair competition, and misuse of trade secrets. His clients have ranged from individual doctors, nurses, and other individual healthcare providers, to ambulatory surgery centers, pharmacies, and drug rehabilitation facilities, to hospitals and Independent Practice Associations (“IPAs”).

Strong Experience with Behavioral Health Providers

Zach has a breadth of knowledge in the behavioral health space. He advises drug rehabilitation facilities on land use, advocating for clients where administrative actions challenge zoning laws, attempting to prevent facilities from operating in their existing location. He litigates out-of-network and in-network reimbursement cases on behalf of addiction treatment facilities and responds to special investigation audits. He has also advised on labor and employment defense matters including those related to racial discrimination, wrongful termination, wage & hour disputes, and retaliation. Clients have come to rely on his insight regarding employee handbooks and labor code issues.


Zach was named to the Southern California Rising Stars list for seven consecutive years (2008-2014) and has been included on the Super Lawyers list for the past four years (2017-2022) and Best Lawyers in America in 2023.

Life Outside the Firm

Outside the courtroom, Zach has utilized that same litigation tenacity to post a sub 6-hour Half Ironman triathlon race. His idea of fun is cycling along Mulholland Drive or the Pacific Coast Highway in a nifty spandex outfit (and helmet, of course) preparing for his next race. For many years, Zach spent his evenings catching live music all around town, but, now a dad, he is resigned to the living room with his Spotify account and a nice single malt.
