About SimonMed

Leading the Way

SimonMed Imaging is one of the largest outpatient medical imaging providers and largest physician radiology practices in the United States. We specialize in using the newest diagnostic imaging technologies and bringing them to the community in an affordable and accessible way. Our logo "See Tomorrow Today" recognizes that new technology can help provide a more accurate diagnosis but needs to be readily available and affordable.

In our physician practice we stress the importance of subspecialty work in order to use this technology in combination with clinical experience to provide the best care. We maintain an active continuing medical education program for our medical communities so that they can share in this goal.

Advanced technology can be expensive but a key part of our mission is to provide it at an affordable cost. SimonMed often saves patients a significant amount in their out of pocket costs and is a national leader in providing cost transparency.

A final part of our mission is to provide care in a supportive and service oriented environment for our patients, referring providers and staff and this reflected in our comfortable office settings and well-trained, compassionate staff.
