SPRINGFIELD, Illinois: A Jacksonville chiropractor who submitted more than 2,000 fraudulent insurance claims and defrauded health insurers of more than $268,000 has been sentenced to one year and one day in federal prison, according to the U.S. Department of Justice.
Rondeau was also sentenced to three years of supervised release following his prison term and ordered to pay more than $268,000 in restitution to compensate for losses caused by the fraud scheme.
His convictions included:
One count of healthcare fraud,
Three counts of mail fraud, and
Five counts of wire fraud.

During the sentencing hearing in the U.S. District Court in Springfield, federal prosecutors presented evidence showing that Rondeau had submitted more than 2,000 separate fraudulent insurance claims.
Prosecutors said the fraudulent claims generated more than $268,000 in improper reimbursements from health insurance providers.
According to the government, each fraudulent claim represented an intentional act requiring Rondeau's direct involvement.
Prosecutors said Rondeau sought reimbursement from insurance companies for:
Medical supplies that never existed,
Services that were never performed, and
Treatments patients never actually received.
Court records further alleged that patients were asked to sign blank treatment forms, which were later used to support fraudulent billing submissions.
Federal prosecutors told the court that Rondeau attempted to obstruct the investigation after learning authorities were scrutinizing his billing practices.
According to testimony presented during sentencing, he used his relationships with patients to persuade some of them to sign false documents in an effort to conceal the fraud.
The government argued that these actions demonstrated a conscious effort to hide the extent of the scheme rather than accept responsibility once the investigation began.
U.S. District Judge Colleen R. Lawless, who presided over the case, highlighted aggravating factors during sentencing.
Judge Lawless noted that Rondeau had previously been caught committing fraud more than a decade earlier. The court further found that he continued submitting false claims even after becoming aware that federal authorities were investigating him for the current offences.
Those findings played a significant role in determining the sentence imposed.
The federal investigation culminated in several legal milestones:
June 2024: Rondeau was initially indicted by a federal grand jury.
August 2024: A federal grand jury returned a superseding indictment against him.
December 2025: Rondeau pleaded guilty to all nine criminal counts.
June 10, 2026: He was sentenced in federal court in Springfield, Illinois.
Rondeau operated chiropractic practices in both Jacksonville and White Hall, Illinois.
While prosecutors detailed the fraudulent billing practices and financial losses linked to the scheme, publicly available court documents have not elaborated on the specific nature of the earlier fraud incident referenced by Judge Lawless.
According to the Department of Justice, the statutory maximum penalties for the offences included:
Up to 10 years in federal prison,
Up to three years of supervised release, and
A fine of up to $250,000.
Up to 20 years in prison per count,
Up to three years of supervised release, and
Fines of up to $250,000.
Although the offenses carried maximum penalties ranging from 10 to 20 years in prison depending on the charge, Rondeau ultimately received a sentence of one year and one day.
Legal experts note that sentences exceeding one year may allow federal inmates to qualify for certain good-conduct time credits.
The case was investigated by the Federal Bureau of Investigation's Springfield Field Office.
Assistant U.S. Attorney Douglas F. McMeyer represented the government throughout the prosecution.
Prosecutors successfully argued that the scheme was deliberate, sustained and continued even after Rondeau became aware of the federal investigation.
