About

Rainier Clinical Research Center was founded in 1991. Since that time we have participated in over 500 Phase I-IV clinical trials involving thousands of patients. Our facilities were expanded to include an inpatient Phase I unit. We began doing research studies primarily in the areas of diabetes and its complications but have since diversified and have conducted studies for a wide spectrum of conditions.
