Contact Information

Arianna is an Associate Attorney working on lawsuits ranging from civil rights violations to commercial litigation. Her practice focuses primarily on complex commercial litigation, including class actions, breach of contract, qui tam whistleblower suits, and a variety of other business disputes. She also assists in handling tort and environmental litigation matters. An empathetic yet persuasive communicator, Arianna understands that litigation is about building a narrative and telling a story, and it involves just as much diplomacy as it does debate.

Before joining DiCello Levitt, Arianna served as a legal intern at top-tier boutique law firms in Los Angeles, where she worked on cases in corporate law, venture capital financing, strategic counseling, and business litigation. In these roles, she drafted stock purchase agreements and briefs, regularly interacted with clients, and performed legal research.

Arianna received her J.D. from Loyola Law School in Los Angeles in 2021 where she was a Loyola Scholar scholarship recipient. During her time at law school, Arianna maintained a host of memberships including the International and Comparative Law Review, the Day Student Bar Association (Student Government) where she served as Speaker Chair, and the International Human Rights Center. During her final year of law school, she was awarded the First Honors Award in Family Law to recognize her outstanding achievement in the subject. Prior to law school, Arianna earned a Bachelor of Arts in English with Honors and double-minored in International Relations and Global Communications at the University of Southern California.
