Managing Director

Mr. Schreiber is the Co-founder of Lumius Capital.


Mr. Schreiber is an attorney, entrepreneur, investor, and philanthropist. Prior to his successful roll-up, restructuring, and sale of a large dairy processing business in the Northeast, he had a long legal career as civil and criminal defense and SEC litigator and trial attorney.

Mr. Schreiber has litigated hundreds of cases—both civil and criminal—with an extraordinary record of success. He has conducted many complex, multi-week jury trials and argued appeals before federal appellate courts throughout the US including California, Mississippi, Virginia, Louisiana, New York, and Connecticut, as well as before regulatory agencies, including the SEC, the New York Stock Exchange, and the former NASD. In the international arbitration field, he won the first case before the Iran/US Claims Tribunal at The Hague, entitled Esphanian v. Bank Tejerat, which established the international law principal of “dominant and effective nationality” for dual nationals suing their former countries. He also won a leading case in the Fifth Circuit Court of Appeals, entitled MacKay v. Waffenschimdt, establishing that a federal court’s jurisdiction to enforce its injunctions by civil contempt was national in scope. He has further advised major corporate clients located throughout the US and Canada, representing a wide array of publicly-traded and privately-held national and international corporations and financial institutions.

Until 1998 (when he retired from active practice), Mr. Schreiber was of counsel to Kramer, Levin, Naftalis & Frankel. Prior to that, he was of counsel at Proskauer Rose Goetz & Mendelsohn from 1987-93. Between 1978-87, he practiced law as one of the founding partners in Schwartz Klink & Schreiber, which he and his partners largely merged into Proskauer. During the late 1970s, he was appointed as Receiver by the Hon. Morris Lasker, US District Judge in the Southern District of New York, in an SEC enforcement action entitled SEC v. Brigadoon, serving for over three years in the capacity. From 1969-74, as an Assistant United States Attorney in the Southern District of New York, he handled a wide variety of criminal investigations and trials both in the Special Prosecution and Securities Fraud Units, many of which cases concerned complex international financial transactions and SEC related matters. During Watergate, he tried then President Nixon and Governor Rockefeller’s doctor for tax evasion, opposing the White House for its resistance to disclosing secret tape recordings. He clerked for Judge Leonard P. Moore, U.S. Court of Appeals, Second Circuit from 1968-69.

Mr. Schreiber earned his Bachelor of Arts in physics from Brown University and received his J.D. cum laude from Columbia Law School. He also graduated from the Owner/President Management program at Harvard Business School. He currently serves on the Board of Visitors of Columbia Law School and is Senior Vice President and Board member of the Washington Institute for Near East Policy, a D.C. based think tank on US foreign policy in the Region. Mr. Schreiber resides in Greenwich, Connecticut with his wife and has eight adult children.
