Currently Enrolling Studies




[toggle_block title=”About Our Program”]
Centennial Research Center has managed over 60 clinical trials ranging from high enrolling flu vaccine studies, to new diagnostic device studies, to complex pharmaceutical trials that involve highly specialized patient bases. We have worked with most major pharmaceutical companies, many of whom come back again and again to our practice because of the quality of our data, availability of our Primary Investigators, ability to enroll different therapeutic areas, and the ease of doing business with us.

The overarching company, Centennial Medical Group, is a Primary Care medical practice working closely with our research division in patient recruitment and management. The practice has 30,000 active patients who are widely diverse in both age and condition and who receive routine care in a variety of specialty areas. The sizable primary care practice allows our research providers to maintain a constant presence on the front lines of patient care.

Our operations and staff are qualified to handle a wide variety of Phase 2 through phase 4 studies, ranging from 1 to 200 study participants, and our research-patient population includes a cross section of ethnic backgrounds, ages, and medical conditions.

Centennial Research Center is committed to world-class research results and the development of quality assurance programs via rigorous staff education and internal audit programs. Continuous quality improvement, an ongoing effort, involves CRC’s entire staff, and bi-weekly training meetings are mandatory, as the key to quality research is constant training. Constant communication between sponsors, CROs, monitors, and Centennial Research Center staff helps provide optimal results.
