On December 10, 2018, the Federal Motor Carrier Safety Administration (FMCSA) suspended and proposed to debar Dr. John Glenn, Dr. Mark Griffis, nurse practitioner Tonya Yawn-Lewis, and drug and alcohol screener Jo Carol White. The suspensions followed Glenn’s conviction for falsification of records and conspiracy to falsify documents, Griffis’ indictment for falsification of records and conspiracy to falsify documents, and Yawn-Lewis and White’s convictions for falsification of records.
DOT-OIG’s investigation revealed that White and Yawn-Lewis routinely falsified medical examination reports and medical examiner’s certificates, and Glenn and Griffis signed DOT Medical Examiner’s Certificates and Medical Examination Reports for commercial driver’s license (CDL) holders without examining the drivers.
DOT-OIG and the Drug Enforcement Administration conducted this investigation with FMCSA’s assistance.
Note: A suspension or debarment frequently covers a specific period of time. Please consult the System for Award Management to determine whether a company or individual is currently suspended or debarred.
