Our story

Built in Nebraska, for the way fleets really run.

Diversified Safety & Compliance is a Nebraska-based compliance, testing, and occupational health company built around a simple idea: employers should not have to piece together critical compliance programs across multiple vendors, disconnected systems, and unanswered questions.

Our roots are in Diversified Drug Testing & Occupational Health Services, a longstanding Nebraska testing and occupational health provider. After working with the business first as a technology partner and consulting client, Derek Aude saw an opportunity to build something broader. He founded Diversified Safety & Compliance and acquired the operating assets of the company, bringing its established testing and occupational health operations together with expanded carrier compliance services, new technology, and a more integrated approach to employer support.

Today, Diversified operates across four connected areas: Carrier Compliance, Drug & Alcohol Testing, Occupational Health, and Compliance Technology.

That structure matters because compliance rarely happens one service at a time.

For an owner-operator or motor carrier, a new driver can involve a pre-employment drug test, Clearinghouse requirements, a DOT physical, an MVR, qualification documents, expiration tracking, and ongoing random testing. When an accident occurs, the questions become even more urgent. Employers need to know whether testing is required, where it can be completed, what needs to be documented, and what happens next.

Diversified was designed to coordinate those pieces.

We provide C/TPA program administration, random consortium management, FMCSA Drug & Alcohol Clearinghouse support, Driver Qualification File management, MVR monitoring, UCR and MCS-150 filings, DOT physicals, post-accident and reasonable-suspicion testing, Return-to-Duty coordination, audit preparation, and access to a nationwide collection network.

For employers outside transportation, we provide drug and alcohol testing programs, post-offer functional testing, fit-for-duty evaluations, audiograms, respirator medical evaluations and fit testing, and other occupational health services that help organizations keep employees safe and ready to work.

Behind those services is something that has become increasingly important to Diversified: better systems.

Technology has been part of the company's strategy from the beginning. We continue to build and improve the systems used to organize records, monitor requirements, manage testing programs, track deadlines, and reduce the administrative work our customers have to manage themselves. The goal is not technology for technology's sake. It is using better systems to make compliance more organized, visible, and manageable.

Today, Diversified serves more than 1,500 carriers and employers from our Nebraska base, with locations in Lincoln, Omaha, and Beatrice, mobile collection capabilities throughout Nebraska and Kansas, and access to more than 3,000 collection sites nationwide through our laboratory and collection partners.

We remain family-owned, Nebraska-based, and locally accountable.

That means when a driver has a problem with the Clearinghouse, a safety manager has a question about a qualification file, an employee needs a physical, or an accident happens after hours, there is a real team behind the program. Our job is not simply to complete a transaction. It is to help determine what needs to happen next and make sure the process gets followed through.

What we're building

Our goal is to make Diversified the compliance partner employers can continue using as they grow.

For an owner-operator, that may mean helping establish the basic programs required to operate correctly. For a growing fleet, it can mean taking responsibility for recurring testing, Clearinghouse administration, driver files, renewals, and audit preparation. For a larger employer, it may mean coordinating occupational health and testing across multiple locations.

The services change with the customer. The principle does not:

Keep people qualified. Keep records organized. Keep compliance moving.

We don't just collect tests and process paperwork. We help manage the deadlines, documentation, systems, and follow-through that make a compliance program work over time.

The Diversified team at work in our Lincoln office
Lincoln, Nebraska — where every Diversified program is built and run.
Our mission

To help carriers and employers manage DOT compliance, drug and alcohol testing, occupational health services, and workforce-readiness requirements through coordinated program administration, responsive support, and practical guidance from a Nebraska-based team.

Our vision

To be Nebraska and the Midwest’s most trusted partner for employer compliance, testing, and occupational health — known for making complex requirements easier to manage through local service, strong program administration, reliable technology, and real people who answer when employers need help.

What we hold to

The principles behind every program we run.

  • Practical Compliance Expertise

    DOT, FMCSA, and employer testing requirements can be complex, especially for carriers and businesses without a full in-house compliance team. We help translate those requirements into clear steps, organized records, and practical support.

  • One Coordinated Approach

    Compliance works better when testing, driver files, physicals, occupational health services, and program administration are not scattered across disconnected vendors. Diversified brings the key pieces together so employers have better visibility and fewer gaps.

  • Support When Timing Matters

    Post-accident testing, reasonable suspicion situations, driver qualification issues, and urgent compliance questions do not always happen during business hours. Our team is built to help employers coordinate next steps when fast, informed support matters.

  • Built for Small Fleets and Growing Employers

    Owner-operators, small fleets, and growing businesses face many of the same requirements as larger organizations, but often without the same internal resources. We provide experienced support scaled to the way real employers operate.

  • Better Systems. Less Manual Follow-Up.

    From testing records and driver documentation to renewal reminders, scheduling workflows, and program tracking, our technology helps reduce administrative burden and keep important compliance details easier to manage.

  • Proactive Program Support

    Strong compliance is not just about reacting when something goes wrong. We help employers stay ahead of upcoming renewals, missing documentation, testing requirements, and program details that can create problems if left unmanaged.

By the numbers

Track record, not talking points.

Built through years of hands-on support for Nebraska carriers, employers, clinics, and safety-focused organizations.

Derek Aude

Founder and CEO

Derek Aude is the Founder and Chief Executive Officer of Diversified Safety & Compliance, where he leads the company’s strategy, growth, technology, acquisitions and long-term expansion.

Derek’s involvement with Diversified began before the acquisition. Through Imogenix, his technology and consulting company, he developed software used to manage DOT compliance and Driver Qualification Files and later served as a technology advisor to Diversified Drug Testing & Occupational Health Services. That relationship gave him a close understanding of the business, its customers and the opportunities available through better systems, technology and operational structure.

Derek later founded Diversified Safety & Compliance with Barb Aude and Tom Nesbitt and acquired the operating assets of Diversified Drug Testing & Occupational Health Services. Since the acquisition, the company has roughly doubled while expanding its services, locations and technology capabilities. Derek has focused on modernizing systems, improving financial visibility, automating manual processes, developing proprietary software, strengthening the company’s operating structure and preparing the business for continued organic growth and future acquisitions.

His broader background spans entrepreneurship, technology, finance, lending, business valuation, software development and acquisitions. He has founded and operated companies across multiple industries, advised organizations ranging from startups to Fortune-scale enterprises, and worked with business owners on technology, capital and growth strategy.

At Diversified, Derek works alongside Chief Compliance Officer Barb Aude, Chief Operating Officer Tom Nesbitt and the company’s compliance, testing and occupational health teams to build a modern, technology-enabled organization capable of serving employers and motor carriers across Nebraska and beyond.

Derek lives in Gretna, Nebraska, with his wife Heather and their four daughters. Outside of work, he coaches competitive fastpitch softball and enjoys spending time with family at the lake, hunting, cooking and playing pedal steel guitar.

Leigh Edwards

Compliance & Testing Specialist

Leigh Edwards is a DOT-certified collector and qualified Breath Alcohol Technician performing DOT and non-DOT testing for Diversified Safety & Compliance, working both in the Lincoln clinic and on-site at client locations. Her collections cover the full range of testing reasons — pre-employment, random, post-accident, reasonable suspicion, return-to-duty, and follow-up — with the chain-of-custody discipline that keeps a result defensible if it's ever questioned.

Leigh's role extends past the collection itself. She manages chain-of-custody and alcohol testing form documentation and correction procedures, tracks specimens through the laboratory and MRO process, handles shy bladder, insufficient breath, and refusal situations under Part 40 protocol, and follows up on pending results so a carrier's records show a completed test rather than an open one. She also supports random selection notifications and completion tracking, helping close out testing cycles inside their required windows, and works directly with drivers and DERs who have questions about what the process involves.

Core functions

  • DOT and non-DOT urine specimen collections, in-clinic and on-site
  • Breath alcohol screening and confirmation testing on evidential breath testing devices
  • Post-accident and reasonable suspicion collections
  • Chain-of-custody and alcohol testing form completion, review, and correction
  • Shy bladder, insufficient breath, refusal, and directly observed protocols under Part 40
  • Specimen handling, lab submission, and result tracking through the MRO
  • Random selection notification and completion follow-up
  • Collection site setup, EBT calibration checks, and supply management for mobile events

Areas of expertise

  • DOT specimen collection (49 CFR Part 40)
  • Breath alcohol testing (BAT)

Fletcher Aude

Compliance Coordinator

Fletcher Aude supports carrier compliance operations at Diversified Safety & Compliance, working directly with owner-operators, fleet managers, and DERs on the recordkeeping requirements of 49 CFR Parts 382 and 391. He handles the day-to-day work that keeps a compliance program current: assembling and updating driver qualification files, running pre-employment and annual Clearinghouse queries, tracking MVRs and medical certifications, and processing UCR and MCS-150 filings.

Much of Fletcher's role is deadline management. He monitors upcoming CDL and medical card expirations, flags missing documentation before it becomes an inspection issue, and follows up with clients until files are complete. He also coordinates consortium enrollments and driver adds and removes, prepares documentation for audits and reviews, and serves as a first point of contact for carriers who need a straight answer about what a regulation actually requires of them.

Core functions

  • Driver Qualification File assembly and maintenance per §391.51
  • FMCSA Clearinghouse full and limited queries, with consent tracking
  • Annual MVR requests, reviews, and driver record retention
  • Medical certificate and CDL expiration monitoring

Angelia Tweedy

Compliance Coordinator

Angelia Tweedy focuses on the program side of carrier compliance, supporting motor carriers through the requirements of 49 CFR Parts 40, 382, and 391. She helps new clients get a compliant program stood up — drug and alcohol policy documentation, driver and supervisor acknowledgments, DER designation, and consortium enrollment — and then keeps that program organized as the operation changes.

Angelia's work concentrates on the situations that require follow-through rather than routine filing. She assists carriers preparing for new entrant safety audits and DOT compliance reviews, assembles supporting documentation and corrective action plans, coordinates return-to-duty and follow-up testing schedules with SAPs, and walks DERs through Clearinghouse violation reporting and the steps that come after a positive result. She is also a regular point of contact for clients working through MCS-150 updates, operating authority questions, and the registration issues that surface when something doesn't process the way it should.

Core functions

  • New client program setup: policy adoption, acknowledgments, and DER designation
  • New entrant safety audit and DOT compliance review preparation
  • Audit documentation assembly and corrective action plan support
  • Clearinghouse violation reporting, query follow-up, and status monitoring
  • Return-to-duty and follow-up testing coordination with SAPs
  • DER guidance on testing determinations, refusals, and required next steps
  • MCS-150 updates, operating authority, and registration issue resolution
  • Client compliance reviews and gap identification
