About  OSCS 

OSCS Drug & Alcohol Testing is owned and operated by myself, Cheryl Mahar. 

 

Over 20 years ago I had the opportunity to learn drug and alcohol testing procedures. After realizing there was a need for services in Washington County, I decided to start my own business offering after hours and mobile testing.

 

With Maine being such a rural state it wasn’t long before my services were in demand all over. I have managed to grow along with the industry and provide a much needed service along with helping smaller companies learn about the required Federal regulations of testing. Meeting new people and learning about the diverse opportunities in Maine has me discovering as much about myself as the clients and companies I work for. I pride myself on being reliable, confident and dependable. I am certified as per DOT Rule 49 CFR Part 40 along with 20 years of experience.
