Failed a DOT drug or alcohol test in Massachusetts? I'm Paul Collette — a DOT Qualified Substance Abuse Professional licensed in Massachusetts as an LADC. I offer same-day virtual evaluations for CDL drivers, MBTA employees, and all DOT-regulated workers throughout MA.

Licensed in Massachusetts
LADC • DOT SAP Qualified
Massachusetts has one of the largest and most diverse transportation workforces in New England. From the MBTA and Logan Airport to the hundreds of FMCSA-regulated freight carriers operating throughout the state, DOT drug and alcohol testing affects tens of thousands of Massachusetts workers.
When a Massachusetts employee fails or refuses a DOT drug or alcohol test, federal law (49 CFR Part 40) requires them to be immediately removed from safety-sensitive duties and evaluated by a DOT Qualified Substance Abuse Professional before they can return to work. The SAP is the only person who can authorize a return-to-duty test and clear an employee to resume their position.
I'm Paul Collette, MS, LADC. I'm independently licensed as an LADC in Massachusetts and have been conducting DOT SAP evaluations since 2019. I offer virtual evaluations for Massachusetts clients — you don't need to travel to Connecticut. Same-day and next-day scheduling is available.
All six DOT-regulated industries operating in Massachusetts
CDL drivers, freight carriers, owner-operators throughout Massachusetts. The state has major freight hubs in Boston, Worcester, and Springfield.
Pilots, air traffic controllers, aircraft mechanics, and other safety-sensitive aviation workers at Logan International, Worcester Regional, and other MA airports.
Railroad workers on Massachusetts freight and passenger lines, including Amtrak, MBTA Commuter Rail, and freight operators.
MBTA bus and rail operators, maintenance workers, and other safety-sensitive transit employees throughout Greater Boston and the MBTA service area.
Natural gas and hazardous liquid pipeline workers operating in Massachusetts under PHMSA jurisdiction.
Commercial maritime workers operating in Massachusetts waters, including Boston Harbor and Cape Cod Canal.
The MBTA is one of the largest FTA-regulated transit systems in the country. MBTA employees in safety-sensitive roles are subject to the same federal DOT drug and alcohol testing rules as CDL drivers. I've helped MBTA employees navigate the SAP process and return to work.
Logan International is a major FAA-regulated facility. Aviation workers in safety-sensitive positions — pilots, mechanics, air traffic controllers — are subject to strict FAA drug and alcohol testing. I conduct FAA SAP evaluations for Massachusetts aviation workers.
Springfield, Worcester, and the Pioneer Valley have significant freight and transportation industries. Virtual evaluations mean distance is no barrier — I serve clients in western MA just as effectively as those in Greater Boston.
Massachusetts CDL drivers who test positive are entered into the federal Clearinghouse. Any DOT employer who runs a pre-employment check will see the violation. The only way to resolve it is to complete the full SAP return-to-duty process.
