Before joining Keller Postman, Brian litigated and tried personal injury, medical malpractice, and wrongful death cases for his own practice and another national plaintiffs’ firm. In November of 2019, Brian played a critical role on the trial team that secured a $58.5 million verdict in punitive and compensatory damages for families who had donated bodies of their deceased loved ones to the Biological Resource Center. The team represented the victims of a scheme to illegally sell parts of donated bodies that were intended for scientific and medical education research. The verdict is one of the largest civil case results in Arizona history.
