Twenty years building research infrastructure, privately owned.
Since 2006, DM Clinical Research has grown from a single site into the largest privately owned clinical research site network in the country, with the stability to invest for the long term.

Two decades, built site by site.
DM Clinical Research is founded in Houston, TX, a single site with an outsized commitment to enrollment and quality.
Network expansion begins across Texas; the proprietary patient database becomes a core enrollment engine.
Therapeutic breadth deepens to 25 areas; bilingual recruitment drives industry-leading diversity.
National footprint reaches the Northeast, Midwest, Southeast, and West, 13 states.
30+ integrated sites, a 1.97M+ patient database, and an AI-first operating layer for feasibility, forecasting, and startup speed.
The values behind a quality record.
Enrollment is a promise
We forecast it, we track it, and we hold ourselves to it, every site, every week.
Quality is non-negotiable
One quality system, rigorous quality systems, and audit-readiness as the default state.
Access for everyone
Bilingual, community-rooted recruitment, 50% Diverse Enrollment is who we are.
