About me

Hassan Zavareei earned his law degree from the University of California, Berkeley School of Law (Boalt Hall) in 1995, where he graduated as a member of the Order of the Coif.

Mr. Zavareei graduated cum laude from Duke University in 1990, with degrees in Comparative Area Studies and Russian.

After graduation from Boalt Hall, Mr. Zavareei joined the Washington, D.C. office of Gibson, Dunn & Crutcher LLP, one of the nation’s premier law firms. In April of 2002, Mr. Zavareei became a founding partner of Tycko & Zavareei LLP.

Mr. Zavareei has handled numerous trials and appeals in state and federal courts across the nation in a wide range of practice areas. In his civil rights practice, Mr. Zavareei represents individuals, groups of employees, and tenant associations in employment and fair housing litigation. Since co-founding Tycko & Zavareei LLP in 2002, Mr. Zavareei has obtained substantial judgments and settlements for his civil rights clients.

In a recent appeal he argued before the Fifth Circuit, Mr. Zavareei successfully overturned an injunction that infringed on his client’s First Amendment rights to free speech.

Mr. Zavareei is currently representing defrauded students and a nationally known test preparation business in high profile trademark, copyright, and unfair competition litigation in California, Texas, and the District of Columbia.

Mr. Zavareei also has significant experience and success in litigating nationwide class actions on behalf of plaintiffs and defendants. For instance, Mr. Zavareei managed the defense of a nationwide class action brought against a major insurance carrier, and, along with co-counsel, negotiated a nationwide class settlement. Mr. Zavareei successfully obtained court approval of the settlement, and supervised the administration of the multi-million dollar settlement fund. Mr. Zavareei is currently litigating several class action lawsuits on behalf of injured consumers.

As part of his environmental and administrative law practice, Mr. Zavareei has obtained significant victories for his municipal and Indian Tribe clients in challenges to federal rulemakings, and negotiated complex settlements in CERCLA cases on behalf of Fortune 500 clients. Mr. Zavareei also led a team of attorneys representing a state agency that was investigated by the United States Attorney’s Office for alleged violations of environmental criminal laws. At the conclusion of the investigation, the U.S. Attorney exonerated Mr. Zavareei’s client.

Mr. Zavareei is admitted to the State Bar of California, the Bar of the District of Columbia, the Bar of the State of Maryland, the District Court of the District of Columbia, and the Circuit Courts of the District of Columbia, the Ninth Circuit, and the Fifth Circuit.

    I have referred matters to Hassan and always look forward to any opportunity to work with him on a case. Hassan is a top-notch attorney with a big firm pedigree, but with a small shop's attention to detail and client service. He also gets results. Hassan has deftly handled both plaintiffs' and defense-side work.
