Tycko & Zavareei LLP was founded in 2002, when Jonathan Tycko and Hassan Zavareei left a large national firm to start a new kind of practice: a private law firm with top tier attorneys serving the public interest. Our attorneys are graduates from the nation’s finest colleges and law schools, including Columbia, Berkeley, Yale, Harvard, Duke, Johns Hopkins, Amherst, and Michigan.

Before joining the firm, our lawyers served in prestigious clerkship’s, worked for the government, served in the military, worked in the public interest sector, or worked for large prestigious law firms. Together, we have established a long and successful record of litigating complex cases. We are based in Washington, D.C., and routinely handle large and complex matters throughout the country.

A wide-range of clients have trusted us with their most difficult problems. Those clients include individuals fighting for their civil rights, consumers seeking redress for unfair business practices, whistleblowers exposing fraud and corruption, tenants’ associations battling to preserve decent and affordable housing, and non-profit entities and businesses facing difficult litigation.



Our lawyers have achieved remarkable results through trials and settlements in landmark cases of great public interest.  Our settlements have netted our clients hundreds of millions of dollars in monetary relief, and changes in practices by banks and other businesses that have real impacts on the day to day lives of our clients.  We have also successfully represented high profile clients such as Dr. Steven Hatfill, who was wrongfully accused of being the Anthrax killer, and Duke basketball legend Christian Laettner, whose revolutionary real estate projects have revitalized downtown Durham, North Carolina.

We are currently litigating dozens of complex cases in state and federal courts across the country.  Our current cases include product liability class actions, consumer class actions, False Claims Act whistleblower lawsuits, and antitrust class actions.  We are highly selective in the cases we accept because we dedicate all necessary resources and effort to each case we litigate.

When widespread unlawful practices are brought to our attention, we carefully investigate the allegations to determine whether we can use our legal skills and the judicial process to compensate the victims and right the wrongs.  While there is not a civil legal remedy for every unlawful or unfair act—especially in light of recent Supreme Court rulings that have curtailed the rights of plaintiffs against corporations—our investigations exhaust every angle to determine whether a legal challenge is appropriate.  These investigations are driven by the information provided to us by the public.  If you have information about any of our investigations, we welcome you to contact us.
