Central Arkansas Finally Has a Drug Testing Partner Built for Employers
Express Mobile Diagnostics was founded to fill a real gap in the market: a locally owned, compliance-driven testing program administrator that brings professional-grade drug and DNA testing directly to Arkansas businesses, without the impersonal service of national chains or the limitations of clinic-based providers.
Why We Started Express Mobile Diagnostics
Central Arkansas employers kept running into the same problem: national chains that treat them like an account number, and clinic-based providers that hand over a result and call it compliance. Neither one manages the program — the random pool, the chain-of-custody documentation, the MRO coordination, the audit trail — that actually protects an employer.
We founded Express Mobile Diagnostics to close that gap. We bring DOT-, FMCSA-, and SAMHSA-compliant drug, alcohol, and DNA testing directly to your office, job site, or terminal, and we manage the full program behind it. Locally owned, compliance-credentialed, and built to withstand an audit — not just to collect a sample.
Meet Our Founders
Co-Founder & Compliance Director
Sherita brings nearly 20 years of professional experience in internal auditing, SOX compliance, finance, and healthcare administration to Express Mobile Diagnostics. She holds a Bachelor's degree in Accounting and a Master's degree in Finance and Healthcare Administration.
Her career has been built around one discipline: making sure organizations operate within the rules, document what matters, and don't leave themselves exposed. That same rigor drives every process at EMD — from chain-of-custody documentation to DOT program administration to how we build employer testing programs designed to withstand an audit.
Sherita launched EMD because she recognized that compliance expertise was exactly what Central Arkansas employers were missing from their drug testing providers, and she knew how to deliver it.

Jordan Brown
Co-Founder & Operations Director
Jordan brings four years of experience as a Business Manager in Health Services at the university level, with a strong background in operations, communications, and organizational management.
She holds Bachelor's degrees in Sociology and Communications and is currently pursuing a Master's in Healthcare Administration.
Her experience managing health services operations gives her a clear-eyed view of what employers, HR managers, and healthcare-adjacent organizations actually need from a testing partner: responsive communication, efficient scheduling, and a process that doesn't create more work for already-stretched teams.
Jordan oversees day-to-day operations at EMD, ensuring every client interaction reflects the responsiveness and professionalism the founders built the company to deliver.
Not Just a Testing Company.
A Compliance Partner.
Most mobile testing providers send a collector and hand you the results. We manage the entire program because compliance is more than a collection.
Compliance-First Foundation
Built by Compliance Professionals EMD wasn't founded by a testing agency or a franchise operator. It was founded by professionals with backgrounds in internal auditing, SOX compliance, finance, and healthcare administration. That means our programs are designed around documentation, defensibility, and regulatory standards, not just convenience.
Boutique, Locally Owned
The Only Boutique TPA in Central Arkansas We're not a national chain managing thousands of accounts from a call center. We're a locally owned Third Party Administrator serving Central Arkansas employers directly. You work with us, not a rotating cast of representatives who don't know your business.
Mobile, Managed, & Documented
End-to-End Program Management From random pool administration to post-accident response to pre-employment screening, we manage the full cycle. Every test is performed by certified collection specialists, processed through SAMHSA-certified labs, and documented to meet DOT, FMCSA, and workplace compliance standards.
Certified Collection Specialist
All EMD collection specialists are required to hold DOT collector certification, Breath Alcohol Technician (BAT) certification, and Oral Fluid testing certification. We don't send uncertified collectors, ever
SAMHSA Lab Partners
We work exclusively with laboratories certified by the Substance Abuse and Mental Health Services Administration — the federal standard for workplace drug testing accuracy and legal defensibility.
DOT & FMCSA-Compliant Procedures
Our DOT employer programs are built to meet all Federal Motor Carrier Safety Administration requirements, including proper collection protocol, MRO coordination, and audit-ready recordkeeping.
Professional Association Members
EMD is a member of the National Drug and Alcohol Screening Association (NDASA) and the Substance Abuse Program Administrators Association (SAPAA) — the leading professional organizations in the drug and alcohol testing industry.
Every collection follows strict chain-of-custody procedures, and results are processed through SAMHSA-certified laboratory partners.
Our Standards Are Non-Negotiable
Every aspect of our collection and program management process is built around federal standards and professional certification requirements.
Invested in Central Arkansas Businesses
Express Mobile Diagnostics is based in North Little Rock and serves employers and individuals throughout the Central Arkansas region. We didn’t launch EMD as an absentee operation, we grew up here, and we live and work in this community.
Our goal is simple: be the most trusted drug testing and compliance partner in Central Arkansas; for the trucking company in Conway, the construction firm in Benton, the staffing agency in Little Rock, and the family in Sherwood who needs a DNA test handled with care
