Why Tycko & Zavareei LLP?

My colleagues at Tycko & Zavareei LLP are whip-smart, with deep experience in class action and whistleblower cases, and they litigate with unparalleled tenacity and creativity to achieve substantial results for our clients and the public writ large. There is no group of attorneys that I would trust more to get the job done--and to do it right.

Mr. Clifford represents plaintiffs in class action litigation challenging corporate greed and practices that place profits over people. He is actively litigating cases against financial institutions, big tobacco, and the payday lending industry over fraudulent, unfair, and unlawful conduct that has harmed millions of consumers. He also is litigating a number of data privacy cases, with an emphasis on data breaches in which the personal information of millions of innocent victims was stolen due to corporations’ lax data security practices. In addition to his consumer protection practice, Mr. Clifford represents whistleblowers who come forward with information about fraud on government programs.

Prior to joining Tycko & Zavareei LLP in 2019, Mr. Clifford was an Associate in the Washington, D.C. office of Covington & Burling LLP, one of the nation’s top defense-side firms. He uses his knowledge of how the other side operates to advance the interests of clients harmed by corporate wrongdoing. During his time at Covington, Mr. Clifford represented corporations in complex litigation and government investigations, including matters involving whistleblower allegations in the healthcare and technology industries. He also maintained an active pro bono practice, representing indigent defendants in immigration and criminal matters.

Mr. Clifford graduated magna cum laude from Georgetown University Law Center in 2015. While in law school, he was an Executive Editor of the Georgetown Law Journal. Following law school, Mr. Clifford clerked for the Honorable Catherine C. Blake of the United States District Court for the District of Maryland. Prior to law school, he worked on several political campaigns following his graduation with honors from the University of Georgia in 2009 with a Bachelor of Arts in International Affairs and a Master of Public Administration.
