Founded in June of 2019, the dynamic duo of Ariana J. Tadler and A.J. de Bartolomeo jointly built Tadler Law from the ground up via a unified blend of vision, determination and talent with two goals in mind – to redefine what it means to be a boutique law firm, and to empower women in the process of doing so.

With 5+ years under their fashionable belts, Tadler Law is savvy enough to know that it’s the people, not the suits they don, that make matters happen.  Fueled by common threads of genuine empathy, grit and unbound energy, the Tadler Team continues to keep people and their personalities at the forefront of every client they represent – a powerful blend of “we care” + “we got this” that continues to win cases.


Ariana J. Tadler is the founding partner of Tadler Law LLP, a
WBENC-certified, women-owned boutique law firm that offers an array of
litigation and legal counseling services. With 30 years’ experience advocating
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 one of the leading women litigators in the country.
Described by Chambers USA as one who “passionately defends her clients’
interests to the greatest extent possible,” Ariana litigates large, complex,
high-profile cases. She is sought after for her unique legal and technological
