He also handled creditors’ rights enforcement and committee work in the United States Bankruptcy Court District of Delaware.

From 2005-2013, David worked at the law firm then known as Bifferato, Gentilotti, Biden & Balick, where he worked his way up from senior associate to a Director and head of the Litigation Department.
