About Keith R. Gosselin and Northeast Onsite Services, LLC

Christine and Keith R. Gosselin

I started in the Drug and Alcohol Testing Industry in 1994. I have been a DOT Qualified Collector, Breath Alcohol Technician and Trainer for a nationwide Third Party Administrator of Drug and Alcohol Testing (TPA). In November 2008 I became an Certified Instructor on the Intoximeters RBT IV.

In July 2014 I made the decision with the help of my beautiful wife Christine to open Northeast Onsite Services, LLC a small company based in Northeast Connecticut that specializes in Onsite Drug, Alcohol and DNA testing. Whether you need a single test or need to test your company,  I am here to help.

In September 2022, we added a full-service Employer Laboratory and collection site to our Brooklyn Connecticut location. Our new business entity is NOS Employer Lab Services.
