Jacksonville Chiropractor Sentenced to a Year in Prison for Healthcare Fraud and Related Offenses

SPRINGFIELD, Ill. - Sean Rondeau, a 56-year-old chiropractor in Jacksonville, Illinois, was sentenced today to a year and a day in federal prison, followed by three years of supervised release, for defrauding health insurance companies of more than a quarter million dollars. His convictions include healthcare fraud, three counts of mail fraud, and five counts of wire fraud.

At the sentencing hearing, the government presented evidence that Rondeau had submitted more than 2,000 separate fraudulent claims. The government noted that each of these fraudulent submissions were the result of an intentional choice by Rondeau and required his direct action. When Rondeau learned he was under investigation, he leveraged his relationships with his clients to convince them to sign false documents in an attempt to hide what he had done.

Also at the hearing, U.S. District Judge Colleen R. Lawless noted that Rondeau committed these crimes after he had previously been caught committing fraud more than a decade ago. Judge Lawless found that Rondeau continued submitting false claims even after he knew he was being investigated for the current fraud. The judge ordered Rondeau to pay more than $268,000 in restitution.

A federal grand jury returned a superseding indictment against Rondeau in August 2024, and he pleaded guilty to all nine counts in December 2025.

The statutory penalties for healthcare fraud are up to 10 years' imprisonment, up to three years of supervised release, and up to a $250,000 fine. The statutory penalties for mail fraud and wire fraud are up to 20 years' imprisonment, up to three years of supervised release, and up to a $250,000 fine.

The Federal Bureau of Investigation, Springfield Field Office, investigated the case. Assistant U.S. Attorney Douglas F. McMeyer represented the government in the prosecution.

On April 7, 2026, the Department of Justice announced the creation of the National Fraud Enforcement Division ("Fraud Division"). The Fraud Division is investigating and prosecuting those who commit fraud against the American people. The Department's work to combat fraud supports President Trump's Task Force to Eliminate Fraud, a whole-of-government effort chaired by Vice President J.D. Vance to eliminate fraud, waste, and abuse within Federal benefit programs.
