Welcome to Paramex.  

We are a locally owned and family operated DOT Services company, located in Chico CA for the past 38 years.  Paramex has a wide range of services to help local companies and drivers with the tools and resources they need to provide a drug-free work environment for safety and DOT compliance.   Drugs and alcohol are not going away, but citizens and business owners should establish areas where these substances must always be prohibited.  Testing brings accountability and trust where we need it most: People who are building our structures, handling our food, watching our children, traveling our roads, protecting our streets,

and making decisions for our city.  


We are happy to offer services that are both needed and appreciated.  Let us help your family, business, school, and health care facility operate and offer a safe place for yourselves and our local community.

Paramex Screening Services is a provider for local and large scale companies.  Being local offers our community and other local companies with a competitive alternative to big internet business by providing a locally owned drug and alcohol testing company in Chico CA.   Even if your testing program or purchase is through another company, you will be sent to our office to complete the collection process and you can be certain it will cost more than it should if not purchased directly or locally.  Take a moment to see how working directly with Paramex will save you time and money.  Drug Testing requires the presence of a professionally trained collection site to perform the chain of custody procedures needed for company and court testing.  Paramex is your one-stop-shop for collections, testing, and reporting.  We offer urine, hair, nail, blood, and saliva testing.  Our testing can be modeled for DOT companies, non-regulated companies, families, probation, court testing, school programs, towing companies, PUC, TSA, 24-7 needs, onsite, supervisor training, city government, police, firefighters, and ambulance services. Our office is partnered with multiple credentialed labs and services to provide fast and state of the art drug testing for our clients.


Why spend more from big internet companies?  Paramex brings affordable (low cost) drug testing and alcohol testing to Chico citizens and companies.  Through Paramex you have access to federal testing labs at much lower costs.  Paramex is small enough to take individual time for its customers to ensure you get what you need, and we are large enough to offer the latest and best tests available in the testing market.
