Trident Clinical Research Services (TCRS) is a site-first clinical research company built by experienced research professionals who understand the realities of study execution because we live them every day.

At its core, Trident is a physician-led clinical research site specializing in late-phase nephrology and internal medicine trials. Based in Apple Valley, California, our team operates within an established and reputable nephrology practice, providing access to a diverse, engaged, and research-ready patient population.

With over 40 years of combined clinical research experience across our site leadership and operations team, Trident has been built on a foundation of compliance, operational rigor, and real-world execution.

What sets TCRS apart is its integrated model.

We bring together something that has never existed in one organization before:
a fully operational clinical research site, strategic consulting, and hands-on site operations support, all under one roof.

We don’t just support research sites, we are a site. That lived experience shapes every process, recommendation, and solution we deliver. From study start-up through execution, our work is informed by firsthand knowledge of the challenges, pressures, and strengths that define successful research programs.

What We Do
• Operate a late-phase clinical research site
• Provide strategic consulting for CROs, SMOs, and emerging and established research sites
• Deliver practical site operations support designed to address real-world challenges

All guided by one mission:
Empowering Sites. Supporting Studies. Elevating Research.

At TCRS, we believe strong sites are the foundation of high-quality clinical research and we are committed to building systems, partnerships, and solutions that help sites perform at their best.
