Jeff Castello represents large corporations in complex food, beverage and consumer product false advertising and consumer product and service litigation and class action claims.

He regularly defends businesses in major cases involving false advertising related to nutrition and health claims, warranty claims, and violations of consumer protection laws. Jeff also has significant experience defending companies that have been accused of violating the Telephone Consumer Protection Act, the California Invasion of Privacy Act, and other federal and state laws relating to website content and accessibility.

In addition, Jeff litigates high-stakes disputes involving claims of unfair business practices, unfair competition, misappropriation of trade secrets, breach of contract, business torts, franchise agreement violations, and IP infringement cases. He has litigated complex cases in the consumer, retail, real estate, satellite television, energy, telecommunications, brokerage, and commercial construction industries, as well as counseled and represented clients in matters pending in federal and state courts, including trials, arbitrations, and appeals. He also has conducted special investigations on behalf of several of the firm’s clients.

After nearly three decades of litigation practice, Jeff has appeared before many federal and state courts across the United States on behalf of national and international companies. While at times trials are the only way to settle a dispute, Jeff has also directly negotiated favorable settlements in numerous litigation and non-litigation matters.

In the event litigation is the only way to resolve his client’s dispute, Jeff has ably examined, cross-examined, and defended witnesses, including CEOs and CFOs, before various tribunals. He has also worked with (and against) nationally renowned experts in the fields of medicine, various scientific disciplines, economics, marketing, and accounting.

Clients value Jeff’s acute strategic insight and inexhaustible problem-solving skills. He counsels corporate boards and senior corporate management on litigation and matters before they reach litigation and takes great pride in finding innovative and cost-effective solutions to the most challenging, sophisticated, and varied legal problems.

Recognized by his clients and colleagues alike for his innate ability to establish immediate rapport, credibility, and trust, Jeff is known for his truly novel approach to dispute resolution, his multidimensional understanding of the industries he serves, and his undeniably successful track record of favorable results on behalf of the firm’s clients.

Jeff consistently delivers practical counsel through every stage of every litigation. Rather than wait until the eve of trial to consider every option with his client, Jeff visits his client’s options throughout the life of a matter. He has tried cases from open to close, and understands every facet of the litigation, including trials and appeals, as well as various alternative dispute resolution processes.

Jeff strives to provide advice that maximizes his client’s chances of a favorable outcome while minimizing the impact on their bottom line and is committed to balancing the cost of litigation with desired results. He is personally committed to establishing relationships of trust not only with his clients and their constituents, but also with judges, juries, arbitrators, and mediators who ultimately hold the fate of the client in their hands.

Jeff served in the U.S. Marine Corps from 1988 to 1992.

I am responsible for persuasively telling my client’s story. To do that, I strive to distill complex issues into understandable winning arguments.”
