Our Physicians
The Radiology Group (TRG), LLC
The Radiology Group (TRG), LLC is the exclusive provider of physician services for the Center for Medical Imaging. TRG is one of the largest subspecialty radiologist physician groups in Oregon. TRG is composed of 28 radiologists, all of whom are fellowship-trained. This means that CMI has fellowship-trained radiologists in each of the subspecialty sections of diagnostic imaging and interventional radiology. Professional services with this level of clinical expertise and imaging technology are rarely seen outside of an academic environment. TRG physicians have been selected not only on the basis of their specialty training and board certification but also for their desire to practice in an environment where they can provide specialty consultation. As medical imaging leaders, TRG continually addresses the dynamic imaging requirements of the healthcare community.
