Meet Our Radiologists

Our radiologists aren't just experts. They're owners. Scottsdale Medical Imaging is fully owned and operated by our 36 board-certified and fellowship-trained radiologists. So when you're here, you're in the care of a team that is 100% vested in providing you the absolute best medical imaging experience. Here, patient care drives business decisions, not the other way around. It's a business model that allows us to always put patient care first and fosters the highest standards of behavior. How refreshing is that?

For over 30 years we have steadfastly pursued clinical excellence, advanced technology, innovation and research - all in an effort to bring our patients an impeccable level of care and our referring physicians an equally impeccable level of service.

Today, in addition to our radiologists providing 24/7 medical image reading coverage at Scottsdale Healthcare hospitals, we are proud to operate 14 state-of-the-art outpatient imaging centers including our Interventional Radiology Clinic which provides patients minimally invasive treatments for a broad range of health conditions, often on an outpatient basis.

Expert diagnoses for exceptional treatment.

Scottsdale Medical Imaging is the most respected radiology practice in the Southwest. Our vision statement is to be nationally recognized as a premier provider of service oriented patient care using medical imaging, image guided intervention and state of the art technology. The knowledge and expertise of our radiologists is unsurpassed. Each one of our physicians is recognized and certified by the American Board of Radiology, most have fellowships in their particular subspecialty area of medical imaging and many hold additional academic positions in leading teaching hospitals and institutions throughout the country.
