Physicians and Management

An Expert Radiology Team

Our expert radiology team has years of experience within the practice and service to regional clients. This results in positive, trusted, professional relationships between our staff and referring physicians. Our clients know what to expect from AR because we’ve built our reputation with them over many years.

To maintain their expertise, each member of our team receives continuing education and hands-on training to learn new techniques and incorporate advanced technologies into the practice, as well as to reinforce our expertise in basic diagnostic procedures.

The AR staff includes experienced board-certified physicians, highly trained radiographers and sonographers, a supportive administrative group, and a visionary management team. Our screening process combines educational, experiential, and personality attributes, which are reflected in AR’s strong teamwork and commitment.
