Shayan Heidarzadeh

Shayan is an experienced litigator who uses his highly analytical mind to develop winning strategies for clients involved in high-stakes litigation in state and federal courts.

Shayan is a litigator who divides his practice between mass tort claims, environmental matters, and complex commercial disputes. He represents clients in both jury and bench trials in state and federal court, and he’s well-versed in defense work in plaintiff-friendly jurisdictions—where he has the skills to still achieve winning verdicts. Shayan is particularly adept at handling cases that rest on highly complex science, and he frequently works with expert witnesses. He knows that victory often depends on a solid understanding of the chemistry behind his argument.

Shayan began his career with a focus on mass tort work, representing equipment manufacturers, suppliers, and premises owners in complex multi-defendant personal injury and wrongful death lawsuits. He has defended clients in matters involving asbestos, talc, construction defect, and premises liability, and he has handled all phases of litigation, from initial complaint to final disposition at trial. While he remains active in the mass tort arena, the experience he gained in these cases led Shayan to expand his practice into litigation involving environmental contamination claims. Shayan represents property owners, manufacturers, and businesses in claims involving soil and groundwater contamination.

In addition to his work with mass tort and environmental regulations, Shayan also represents clients in general commercial litigation and business disputes. He handles breach of contract allegations and other contract disputes as well as litigation involving real property, including title disputes and allegations of real estate fraud.

A highly analytical attorney, Shayan excels at digging into cases and facts and finding alternative sources of exposure. He’s especially passionate about trial preparation and setting a client up to win, with a gift for anticipating his opponent’s next move in court. Shayan takes care to keep overall client goals and needs in mind at every stage, setting a compatible strategy from the very beginning of litigation.

In addition to his client work, Shayan devotes time to pro bono matters and supports diversity, equity, and inclusion efforts inside and outside the firm. He is an active member of Husch Blackwell’s APISWANA (Asian, Pacific Islander, Southwest Asian, North African) Employee Resource Group and values participation in the group’s mentoring program as both a mentor and mentee.
