About DCOL

DCOL Center for Clinical Research began conducting clinical trials in 2005. We are a dedicated research department of Diagnostic Clinic of Longview, a large, multi-specialty group practice consisting of over 60 physicians. Longview is located in Northeast Texas with a population of about 82,000. However, due to the large number of surrounding towns and communities we draw patients from a total population of about 250,000. Our group practice has an active database of over 100,000 patients. The research department has access to EMR, so we are able to run searches and recruit specific patient populations.

Being a department of Diagnostic Clinic of Longview, we also have easy access to other departments such as radiology services, bone density testing, sleep lab, spirometry, complete pulmonary function testing, and Echocardiograms. 

In addition, we use only the Central IRB requested by the Sponsor.
