The Weinhardt Law Firm specializes in the investigation and defense of white collar criminal matters. The U.S. News/Best Lawyers ranking of "Best Law Firms" rates the Firm as a First Tier law firm in white collar criminal defense-governmental investigations. As the Des Moines Business Record notes, founding partner Mark Weinhardt has "carved a reputation as one of the state's premier white-collar crime litigators."

The Firm represents individuals and businesses in every manner of white collar criminal investigation and prosecution. While these representations are often high-profile, many never see the light of day. The Firm is routinely involved in pre-indictment investigations in which it attempts — and frequently succeeds — in persuading the government to forego criminal charges or to dispose of a matter less punitively than it originally contemplated.

When charges are filed, the Firm defends its clients vigorously. The Firm's attorneys have an impressive track record of defending criminal charges at trial and on appeal. And in cases where a guilty plea cannot be avoided, The Weinhardt Law Firm's attorneys have an exceptional history of obtaining favorable sentencing results for their clients.

A sampling of criminal cases handled by the Firm's lawyers is available here. The Weinhardt Law Firm's attorneys have handled a broad range of white collar criminal matters, including cases alleging antitrust violations, trade secret theft, immigration fraud, violations of the Foreign Corrupt Practices Act, environmental crime, public corruption, bank fraud, mail and wire fraud, securities fraud (including insider trading), health care fraud, false statements to the government, vote fraud, food safety violations, illegal arms exports, tax evasion, and agricultural lending and insurance fraud.
