Ariana Joyce Tadler

Ariana J. Tadler is the founder and managing partner of Tadler Law LLP. With over 27 years of legal experience, she advocates for consumers and investors against corporate fraud and abuse while litigating and managing securities, consumer and data breach class actions, and complex litigation. Ariana is considered one of the leading women litigators in the country. She is described by Chambers USA as one who “passionately defends her clients’ interests to the greatest extent possible.” She is sought after for her unique legal and technological acumen and case management skills.

Ariana graduated from Hamilton College with a Bachelor of Arts degree and received her law degree from Fordham University Law School in 1992. She is a tough, solution-driven negotiator with a creative and robust aptitude for resolving disputes, Ariana is regularly appointed by courts to leadership positions in large, complex federal, multi-district, and state coordinated proceedings because of her extensive experience managing complex litigation. Ariana is also recognized as one of the nation’s leading authorities on electronic discovery and pioneered the establishment of an e-Discovery Practice group within a plaintiffs’ firm structure more than 15 years ago. Her exceptional skills and knowledge in the field of e-Discovery have distinguished her from her litigation peers. She remains the only plaintiffs’ lawyer to be ranked repeatedly as a Band 1 e-Discovery Practitioner by Chambers and Partners in the Global-USA and USA-Nationwide categories. In 2017, she was appointed by United States Supreme Court Chief Justice Roberts to serve on the Federal Civil Rules Advisory Committee, and in December 2020, Chief Justice Roberts renewed her appointment to serve a second term.
