Habib Nasrullah


P. 303.244.1960 | F. 303.244.1879


A former Assistant U.S. Attorney, Habib Nasrullah maintains an active trial practice in high exposure tort and commercial cases. He regularly represents global clients in trials and government investigations. Habib is a Fellow of the American College of Trial Lawyers.

Habib also serves as trial and national coordinating counsel on commercial, mass tort, and complex product liability lawsuits, including multidistrict litigation. Habib’s clients include Fortune 100 and other leading companies, and he has substantial experience in federal and state courts across the U.S.

Habib’s background as a federal prosecutor makes him particularly valuable to clients in civil cases that involve a parallel criminal investigation. Habib strives to resolve these matters in the earliest possible stages, sparing clients the potential of facing criminal charges or intense public scrutiny. Habib also conducts internal investigations and counsels individual and corporate clients on a variety of federal and state compliance issues in the healthcare, technology, aviation, and the food and beverage sectors.

A Fellow of the American College of Trial Lawyers, Habib frequently manages mass tort litigation involving dockets of several thousand cases across multiple jurisdictions. He has been involved in defending healthcare industry clients against thousands of claimants alleging catastrophic personal injuries. He has represented food producers in various disease outbreaks allegedly linked to contaminated food products that have resulted in multiple deaths, including the deadly Listeria outbreak linked to Colorado cantaloupes, which sickened hundreds and killed 33 people.

In every engagement, Habib works with clients and local counsel to conceptualize and implement coherent and effective litigation plans for multidistrict and complex litigation. Clients frequently retain him to try cases involving sophisticated expert and evidentiary issues with potentially high exposure when trial is imminent.
