Who We Are


The Founding of DxR Development Group

The DxR Development Group's roots are academic. Our company started in 1990. At that time, there was a need to meet a specific instructional need related to problem-based learning education at the Southern Illinois University School of Medicine (SIU-SOM).

To meet this need, J. Hurley Myers, Ph.D., professor of Physiology and Internal Medicine and Kevin Dorsey, MD., Ph.D., clinical professor of Internal Medicine while on faculty at SIU-SOM, teamed up with Eldon Benz, a software engineer. Together, we developed Diagnostic Reasoning, a software package designed to provide students with the ability to practice the patient encounter and to give faculty a record of how each student reasoned through the patient problem.

The 1990 version of Diagnostic Reasoning was rudimentary by today's multimedia standards. Nonetheless, the value of Diagnostic Reasoning's features was quickly obvious within the SIU School of Medicine. Interest from outside SIU-SOM increased to the point that it became necessary to transfer our software development and marketing effort to the private sector. Accordingly, we incorporated as DxR Development Group, Inc., and moved our operation to the Dunn-Richmond Economic Development Center in July of 1992.

DxR Development Group and Novartis Medical Education

It became clear almost immediately after entering the private sector that to survive in this very competitive medical education software market, the DxR Development Group needed something more than patient simulation software. To that end, we negotiated and signed a long-term contract with Ciba Medical Education and Publications, now Novartis Medical Education, located in East Hanover, New Jersey.

DxR Products and Services

Since incorporating as DxR and partnering with Novartis, we have produced and released several important products for Novartis based on the Frank Netter, MD., illustrations.

These products include:
