Meet Ann

Dr Ann Olivarius  KC (Hon) OBE

Dr Ann Olivarius  KC (Hon) OBE

Chair of the Executive Committee

Ann Olivarius has been fighting for people who have been harassed, abused, and discriminated against since before she was a lawyer. At 22, as a student at Yale, she became a plaintiff in Alexander v. Yale, the 1977 landmark case that established for the first time that universities who do not do anything to curb sexual harassment are committing illegal sex discrimination under federal law. Nearly fifty years later, she remains more committed than ever to the belief that when institutions seek to silence those they harm, it is a lawyer’s job to give them a voice – in court, in public, on the record.

A lawyer who has courageously advanced the cause of justice, and improved life opportunities, for hundreds of millions of women, blacks, and disadvantaged, worldwide.

In 2011, Ann joined forces with leading US child abuse litigator Jeff Anderson to bring historic child sex abuse cases against powerful institutions and form new paths to justice for British victims. She has since helped hundreds of survivors of traumatic abuse to bring cases against the Catholic Church, major schools, care homes, the Church of England, the Methodist Church, Harvest Christian Fellowship, and others on both sides of the Atlantic.

Ann has also been a trailblazer in fighting sexual harassment and discrimination in the workplace. She forced the University of Rochester to pay out $9.4 million – one of the largest sexual harassment awards against a US research university – after sparking a national conversation about power dynamics in American academia. Ann’s work saw her named by Nature as one of the 10 people who had the biggest impact in science that year, while two of her clients became TIME magazine People of the Year for their role in the lawsuit. 

She was among the first lawyers to identify online image abuse as a significant problem. Her early work in this field led McAllister Olivarius into the uncharted territory of online safety legislation. When Chrissy Chambers came to Ann after intimate images of her had been posted online without her consent, there was no civil precedent in England and Wales for what had been done to her. Ann brought the case anyway and won. The judgment that followed helped persuade Parliament to make non-consensual intimate image sharing a criminal offence. The law Ann helped to change has protected people ever since. 

In 2022, Ann was named an Honorary King’s Counsel – one of the rarest distinctions in the English legal system – in recognition of her leading role in the fields of women’s rights, sexual harassment, and sexual abuse, and for having played what the Ministry of Justice described as “an instrumental part in lobbying Parliament to pass laws against the disclosure of non-consensual private images.” 

She has been recognized by the ACLU, by Yale Women, and been named OBE (Officer of the Order of the British Empire) for her work. She holds law and business degrees from Yale and a DPhil in Economics from Oxford, where she was a Rhodes Scholar. She is a frequent contributor to British and American media and continues to speak, write, and advocate publicly on the issues her clients face. 

Ann runs McAllister Olivarius alongside her husband and law partner Jef McAllister, whom she met as an undergraduate at Yale. Together, Ann and Jef have spent nearly 50 years fighting to make the world a better place. Based on her own experience as a plaintiff and thirty years of legal and trial experience, Ann knows that justice doesn’t come without courage. Each time someone contacts McAllister Olivarius looking for justice, she hopes she can help.
