Federal compliance expertise you can rely on
Charlotte Nwogwugwu, DrPH, CEAP is a U.S. Department of Transportation qualified Substance Abuse Professional based in Baltimore, Maryland. She performs the federally mandated evaluations required under 49 CFR Part 40 for safety-sensitive employees across all DOT-regulated industries.
When a safety-sensitive employee fails or refuses a DOT drug or alcohol test, federal law requires they complete a SAP evaluation before returning to duty. Charlotte provides that evaluation — along with the education, referral, and follow-up coordination required by federal regulation.
