Testimonials
The DISA Contractors Consortium program has helped SEPCO effectively monitor compliance both at the contractor company level, as well as by individual employee. Their real-time compliance solutions reduce risk and exposure for Shell employees and contractors, while assisting in the drive to Goal Zero.

Thank you for all the support we have received here at Valero Three Rivers throughout 2009. I really appreciate the professionalism concerning contractor screening and in the answers to my many questions.
I found that working closely with DISA representatives during our Turnarounds with the random drug screens has made this a safer facility to work at. Having DISA here onsite during this time speeds up the collection and gets the contractors back at their worksite with the minimum of delay to work schedules.
One thing that I really like about the system is that a contractor may have tested for a different facility but can come in here and work without having to go and retest for this facility. This makes for quicker turnovers on our projects and shortens delays.
Once again I would like to thank everyone involved in making our worksite a safer place.

We have been using DISA for over ten years and they have continually proved that they are an industry leader in employee drug screening. Their onsite collection facilities at the refinery jobsites keep our downtime to a minimum. Results are delivered in a very timely manner and if there is any kind of issue, they are quick to resolve it. The DISA website is easy to use and has a lot of useful information that we have referred to on several occasions. The times that we have had to deal with the MRO department, they have been very helpful in getting our people back to work.

Since I started at Mustang Engineering in March 2008, DISA, Inc. has been our preferred choice of vendor to handle our pre-employment and client required drug and alcohol testing programs. Their online database, website accessibility, and client service has set them apart from the other vendors I have worked with in the past. Their commitment to improving processes and offering new products and services makes me confident that I won’t be changing providers anytime soon.

Veolia ES-Special Services division recently contracted with DISA and my experience has been A++. They are very quick to answer any and all question's that may arise. They have also assisted in launching our Reasonable Suspicion Program effortlessly. The training department, customer service and my account representative are top rate and ensure I have complete compliance in all of my programs.

DISA in this past year has been instrumental in assisting in the implementation of a revised corporate policy for testing, along with changes in the DER roster. All issues that arose during the implementation and changes were handled expediently.

Well we just started with the backgrounds so we don’t have much history yet but we have really good results with our DISA drug screen program. The information available online is a great resource for us and is very user friendly.

DISA has given us the ability to “one stop shop” by providing efficient background and drug/alcohol services. This has saved us a tremendous amount of time, sometimes days, and several hundreds of dollars when compared to our previously used carrier. All of these attributes, combined with the outstanding customer service, makes DISA the only choice for ALL of our needs!

I have to say that DISA has been a life-saver in this situation with the knowledge your company has, the efficiency in setting up the account, and ease of use on the website. Thank you again for your assistance! I will be sure to push to use DISA in the future for any of our background check needs.

This is coming from a fast moving crane company. When we've needed DISA's assistance, BAM! You guys have been there. We all know that time is money, and if we have operators standing by who are not cleared to enter a specific site, then we at Maxim Crane Works are losing money. DISA helps to prevent and assist with lock-outs by being there when called upon. Thanks for your help....You've got some good team players.
John De La Garza
Subregion Safety Manager
Maxim Crane Works
As a company with multiple departments requiring multiple policies to be compliant, DISA has become an extension of our operation. Through this relationship, we have secured larger contracts and set ourselves apart from our competitors. With the continued support provided from the Business Development, Customer Support, Training, and Compliance personnel, I am confident we will continue to grow together.
