As a two-time Olympic Gold Medalist and World Cup Champion, I am fortunate to have a platform from which to fight for the values I believe in, hold dear, and try to live by – – to be a trailblazer and an activist for equal pay, athletes’ rights, diversity, and gender equality. 

A J de Bartolomeo was my advisor, advocate, expert class action attorney, and critical member of the legal team that represented me in my Equal Pay Act and Title VII discrimination case against the US Soccer Federation. Our priorities and values aligned in my quest for equal pay in sports and the restoration of integrity within the Federation. Standing up to U.S. Soccer in court was an achievement personally and professionally, and our fight for my goals of equal pay and honor continues. A J showed up for me with courage, integrity, and effective legal representation, even when it was not the easy path. Because the righteous path is seldom the easier one.

“From the start of the eDiscovery revolution, Ariana J. Tadler has been recognized as one of the leading plaintiff attorneys in the United States. She is respected by lawyers across the United States and Canada for her intellect, her work ethic, and her creativity.”

Larry Center, former Georgetown University Assistant Dean of Continuing Legal Education

“As a longtime board member, former board chair and event committee co-chair, Ariana has provided Mobilization for Justice with invaluable advice and counsel in development, communications, community-building, and project execution. Ariana’s attention to detail, clarity and no-nonsense business acumen has helped us build strategic partnerships, fundraise, and work through challenges. With Ariana as co-chair of our 60th Anniversary gala, we raised over $1 million – a new milestone for us – and secured several new sponsors.”

Tiffany Liston, Executive Director Mobilization for Justice, Inc.

“I felt instantly part of a family of experts that was willing to offer support, advice, and action and empowered me when I was at my weakest. The team energized me with their positive outlook and shear strength. They gave me a voice when I didn’t have one, they gave me multiple angles to think about, they made things easy for me to understand. I was aware of all plans before they happened.  My case had so many twists and turns. Ariana called me with updates, shared the strategy ahead of time, and when she thought of something or an angle, she called me to ask.  I just felt protected, but it made me feel like no one could mess with me with Ariana on my side. I feel very lucky.”
