He focuses on identifying and securing pro bono opportunities and partnerships for Proskauer lawyers and ensuring widespread participation in these projects.

Bill has robust private and public sector experience and a strong criminal and civil background. He has worked extensively on government investigations and white collar criminal matters, as well as complex civil litigation in federal and state courts. He also served as an assistant U.S. attorney in the Southern District of New York, where he led criminal investigations, conducted trials and handled Second Circuit appeals.

Throughout his career, Bill has dedicated himself to the promotion of equal access to justice through pro bono service, particularly in the areas of family court, anti-trafficking, and criminal reentry.

Bill served as lead counsel on behalf of three legal services organizations challenging New York State’s “Host Homes” regulations, which created an unauthorized shadow foster care system. In a unanimous decision, the New York Court of Appeals struck down the regulations for failure to provide important safeguards, including appointment of counsel and judicial oversight.

Bill serves as counsel to the New York State Anti-Trafficking Coalition. In that capacity he has been a strong advocate for changes in the law and public policy to protect victims of human trafficking and bring perpetrators to justice. He also represents individual clients in this area, including a successful federal lawsuit brought on behalf of a trafficking victim against her traffickers. For his work, he was named by domestic violence nonprofit Sanctuary For Families as one of “New York’s New Abolitionists.”
