Sadie Hillier

Sadie is passionate about protecting clients’ rights and holding corporations accountable. She represents consumers primarily in class action lawsuits with a special emphasis on privacy and data breach litigation.

Prior to joining Gibbs Law Group, Sadie spent two years as an Assistant Federal Public Defender representing indigent clients on death row in late-stage federal appeals. She then transitioned to civil law, representing clients in a variety of civil rights cases centered on reproductive rights, First Amendment, police brutality, LGBTQ rights, and the right to privacy.

Sadie graduated from Harvard Law School in 2020. While in law school, she was heavily involved with and served as the Executive Director of the Harvard Prison Legal Assistance Project, where she spent three years advocating for the rights of incarcerated people in disciplinary and parole hearings, through policy advocacy with the Massachusetts legislature, and in civil rights lawsuits. Sadie was also on the board of the Harvard Civil Rights—Civil Liberties Law Review, served as President of HLS Child & Youth Advocates, and completed a variety of public interest internships and externships, including at the Civil Rights Division of the Department of Justice, Civil Rights Corps, and the Orange County (California) Public Defender. At the Orange County Public Defender, Sadie worked on the case that ultimately made public the fact that Global Tel Link (GTL), the nation’s largest jail and prison phones vendor, had a history of nationwide system problems causing it to illegally record thousands of attorney-client phone calls.
