Rainier Clinical Research Center offers access to the latest clinical trials

With more than 1000 clinical trials completed over three decades, we've been the trusted choice for Phase 1-4 clinical trials involving thousands of participants. Our full-time, dedicated, board-certified investigators work with a team of clinical trial professionals in our state-of-the-art facility in Renton, Washington to complete studies in a wide range of therapeutic areas.

Established in 1991, Rainier Clinical Research Center (RCRC) brings more than 30 years of experience conducting clinical trials. With origins in endocrinology and a transition in 2012 to a fully research-focused site, RCRC has built a strong reputation for scientific expertise, operational efficiency, and high-quality participant care. Now part of Curiex, RCRC brings decades of specialized experience and a deep commitment to compassionate, participant-centered care across a broad range of indications.

1. Proven Leadership and Industry Pedigree

RCRC is led by a seasoned team of executives with decades of direct site operations, network integration, and clinical outsourcing experience.

2. Differentiated Ownership Model

Unlike traditional SMO “roll-ups,” Curiex is not a consolidation of acquired assets. Instead, Curiex’s structure preserves site ownership and independence, aligning incentives and maintaining the entrepreneurial spirit that drives recruitment performance, therapeutic expansion and participant engagement. Curiex was built by sites, for sites.

3. Integrated Enterprise Infrastructure

Curiex delivers operational consistency and financial transparency through fully harmonized systems across accounting, finance, HR, IT, quality, and marketing—without compromising local site agility.

4. Scalable Platform

RCRC is one of 13 high-performing sites under Curiex, which offers immediate scale with strong organic growth potential. Standardized processes, common technology infrastructure, and central management allow for expansion and seamless integration of future sites.

5. Deep Investigative and Therapeutic Expertise

Curiex sites conduct trials across a wide range of therapeutic areas with medical directors providing oversight and network-wide quality alignment in areas such as cardiology, dermatology, endocrinology, OB/GYN, psychiatry, rheumatology, sleep medicine, and beyond.
