Pat McInerney is a partner in the Spencer Fane White Collar and Government Investigations practice. He brings over two decades of experience as a trial lawyer, having first-chaired many high profile and complex cases in federal and state courts. As a former state and federal prosecutor, last with the Organized Crime Strike Force Unit of the United States Attorney’s Office for the Western District of Missouri, Pat’s background prosecuting organized crime and public corruption give him a unique understanding of investigative and prosecution priorities, and allow him to counsel individuals and companies facing federal criminal or civil investigation.

Pat’s experience includes cases involving allegations of business disputes, healthcare and tax fraud, commercial merchandising practices act violations, criminal trade secret violations, and general criminal violations and civil disputes. He provides representation to people and companies in the private and public sectors, in matters ranging from high stakes civil and criminal litigation to government proceedings and internal investigations. Pat is retained by clients to design and execute internal and parallel investigations, develop crisis response protocols, and to coordinate defense tactics and strategy. He also advises individuals in private and public leadership positions regarding regulatory and law enforcement response. Most recently, Pat concluded the successful representation of a group of businesses that were the target of a federal criminal investigation by the Internal Revenue Service and the Tax Division of the U.S. Department of Justice. The investigation – which lasted nearly seven years – closed with no charges or penalties.
