Allessandra Rose Johnson is an associate in O’Melveny’s New York office, where she focuses on trial work and internal investigations for clients in a variety of industries, including entertainment, insurance, energy, and technology. Allessandra has served on trials in New York federal and state court defending a large insurance company in coverage disputes. She also has experience representing a technology company in an ICC arbitration and a large energy company in an FCPA investigation, as well as conducting internal investigations for clients in the investment-management and life-sciences spaces.

Allessandra also devotes significant time to her pro bono practice, where her work has included appearing in Queens Family Court and Immigration Court to successfully secure Special Immigrant Juvenile Status and participate in asylum proceedings for a young woman from Honduras who entered the United States as an unaccompanied minor, and representing a man whose prior murder conviction in Louisiana has been overturned on constitutional grounds in an upcoming retrial.

In her practice, Allessandra draws on her experience as a clerk for then-Chief Judge Leonard P. Stark at the US District Court for the District of Delaware. Prior to her career in the law, Allessandra was a professional musician, having extensively studied classical piano performance for decades.
