“My major objective is to expand upon the good work of this office by preventing, detecting and prosecuting all thefts and frauds,” said Walpin. “The reality is that such misconduct takes precious resources away from deserving people, the same way the theft of a welfare check hurts a single mother who needs that money to buy milk for her children. For that reason, this office will seek out and ensure sanctions for all wrongdoing involving Corporation funds.”
Walpin said his other major goal is to “assist the Corporation in making its services efficient and accessible for all national service stakeholders.”

He spent more than 40 years as senior partner and, more recently, of counsel to New York-based Katten Muchin Rosenman LLP.
Mr. Walpin has represented a wide range of clients, including large public corporations, securities brokerage firms, accounting firms, law firms, banks in lender liability claims, and individuals, both American and foreign, in securities litigations, employment litigations, criminal prosecutions, and investigations by the United States Securities and Exchange Commission. Both as an Assistant U.S. Attorney and in his law firm, he was frequently called upon to investigate fraudulent conduct.
