Cardozo School of Law in 1996, where he was an editor of the Cardozo Law Review.  Marc started his legal career at the prominent New York City law firm of Mudge Rose Guthrie Alexander & Ferdon and has practiced law at AmLaw 100 law firms in New York City and San Francisco.  


In addition to his award-winning transactional legal work, Marc has had articles and legal papers published in the Delaware Journal of Corporate Law, the Akron Journal of Constitutional Law and Policy, the Cardozo Law Review, the Mississippi College Law Review and the Chapman Law Review, among other publications.  

Marc has practiced before the United States Supreme Court with two amicus curiae filings in the Hobby Lobby Obamacare case and the 2015 same sex marriage case.  Marc's works have been referred to or cited in opinions by the supreme courts of both the United States and Israel and have received widespread media coverage. In the Supreme Court of Israel's 2015 ruling upholding Israel's anti-boycott law, Marc's paper on the BDS movement was cited by both the majority and dissent.  


Marc's work on the legal standing of BDS movement activity has also been instrumental in the enactment of anti-discrimination laws in the United States, most recently with regard to California's AB 2844.  Marc can be reached at Info@Zachorlegal.org.

Why "Zachor"?


​The name "Zachor" comes from the Hebrew word for "remember" and it is often associated with the need to remember that which led to the slaughter of six million Jews in Nazi Europe.

As the son of a holocaust victim, Zachor is an important principle in Marc's life.  The entirety of Marc's mother's family, other than her, her father, mother and one uncle, perished after the Nazi regime invaded their native Czechoslovakia and rounded up Jews.  While Marc's mother was also taken into custody by Nazi agents, a quirk of family history intervened.  Marc's maternal great-grandfather had his family in Europe in the mid-1800s to start a business in the United States and he obtained American citizenship.  Due to a death in the family, Marc's maternal great-grandfather had to move back to Europe shortly after obtaining American citizenship, 

When the Nazis were processing Marc's mother's family for shipment to concentration camps, they discovered that Marc's grandfather had putative rights to American citizenship due to his father having been a naturalized American citizen.  Because of this, Marc's grandfather was valuable to the Nazis for use in a prisoner exchange between the United States and Germany.  Though it took over a year, during which time Marc's grandfather was sent to the United States to claim citizenship while his wife and young daughter were left behind in Nazi custody, Marc's mother and grandmother were ultimately sent to the United States as part of the prisoner exchange and their lives were spared. The Ellis Island manifest for the ship that brought them to United States is the background image on this website.

Were it not for the cooperation of American authorities in agreeing to a prisoner exchange, Marc's maternal family would have been left in Europe to be killed in Nazi concentration camps.  Marc thus owes the United States a debt that he can never repay. 


Through founding Zachor Legal Institute, we hope to preserve and strengthen the exceptional American ideals that saved his mother's life. 

The American ideals that we seek to preserve can best be described as those that are the underpinnings of what used to be the American federal constitutional republic.  These ideals form the basis for freedom from discrimination and the inherent right of each person to live a life according to his or her own beliefs.
