When a business or individual faces federal investigation or is embroiled in a business dispute or tort claim, David Niemeier’s extensive federal court experience in commercial and white-collar defense helps him to vigorously represent client interests.
David has successfully represented individuals, developers, financial institutions, health care companies and religious organizations in civil actions in state and federal courts across the country, dealing with matters including tort claims, class actions, federal and regulatory investigations, and securities litigation. He has advised and defended those implicated or charged with federal criminal offenses including conspiracy, insider trading, mail and wire fraud, and money laundering.
Drawing on his previous work experience at a federal court and in a prosecutor’s office, David understands the process those facing a potential white-collar indictment or investigation will encounter. He applies that knowledge to crafting legal strategy and advising clients on how to exercise their rights when government agents appear at their home or business.
Before joining the firm, David spent two years as a judicial law clerk for Judge Catherine D. Perry of the U.S. District Court for the Eastern District of Missouri. The experience provided firsthand exposure to how white-collar cases move through the court system, as well as extensive knowledge of federal rules and practice.
