Zachary Crosner is the founder and President of Crosner Legal, a multi-state plaintiff-side practice dedicated to advocating for employees and consumers. Establishing the firm in 2013 at the age of twenty-seven, Zach started with no cases and an unlikely partner: his late father, Michael Crosner. An accomplished trial lawyer with decades of jury experience, Michael humbly entered an entirely new field of law to help fulfill their shared dream of building a practice together. Building the firm brick by brick, they grew it methodically—one case, one hire, and one office at a time. Although Michael passed away in 2023, the rigorous standards he set and the integrity he embodied remain the foundational ethos of the firm today.
During the firm’s first decade, Zach was heavily involved in the day-to-day trenches of complex litigation. Drawing on early trial and litigation experience in catastrophic injury and civil rights cases at prominent California plaintiff’s firms, he brought an aggressive, tested background to the negotiating table. He has since been appointed lead or co-lead class counsel in more than 100 complex actions and has personally negotiated a multitude of multi-million-dollar class settlements.
As Crosner Legal has scaled, Zach’s role has naturally evolved from a day-to-day litigator to the chief architect of the firm’s strategy and geographic expansion. Drawing on his background as an entrepreneur and founder of multiple businesses, he brings an operator’s fluency in marketing, technology, and business strategy to class action law. This data-driven approach allows the firm to effectively identify and reach workers and consumers who may not even know their rights have been violated. Operating with the agility of a modern enterprise, Zach has spearheaded the firm’s multi-state expansion, assembling elite litigation teams and corporate infrastructure that allows the firm to manage hundreds of active class and complex actions nationwide.
Beyond securing financial settlements, Zach is deeply committed to ensuring that illegal corporate practices are permanently corrected. He views complex class action litigation as a vital check on the system—a mechanism to force corporate policies into strict compliance with the law and create lasting change for the people impacted.
