Federal prosecutors in St. Louis are seeking to identify potential victims connected to an ongoing case against physician David A. Parks, clinical manager and research coordinator James M. Bilderback, and front desk assistant Michelle J. Scheer. The three worked at a clinic located at 3960 Lindell Boulevard in St. Louis.
A federal grand jury indicted the trio in July 2024 on charges alleging that from July 6, 2016, through December 31, 2021, they conspired to prescribe controlled substances outside the usual course of professional practice and without legitimate medical purpose. According to the indictment, their aim was to increase patient numbers and maximize profit.
The indictment also claims that Parks and Bilderback conspired to defraud Medicare, Missouri Medicaid, and private insurers by billing for services that falsely listed Parks as the provider—including during times when he was reportedly out of the country.
On August 15, 2025, U.S. Magistrate Judge John M. Bodenhausen ordered alternative notification procedures so members of the community who may be affected can learn about their rights.
Community members who believe they may have been harmed by illegal prescribing or fraudulent billing practices involving Dr. David A. Parks, James Bilderback or Michelle Scheer are encouraged to contact the Victim-Witness Unit at (314) 539-2227 at the U.S. Attorney’s Office for the Eastern District of Missouri.
Former patients or their families may still experience consequences related to these alleged activities. The victim-witness program offers information and support throughout federal prosecutions.
Case updates will be available on the U.S. Attorney’s Office website at https://www.justice.gov/usao-edmo/pr.
