About Us

Who We Are

  • DxR Development Group, Inc. was founded in 1992 by Professor Hurley Myers and Dr. Kevin Dorsey of the Southern Illinois University Medical School, and software engineer Eldon Benz. Myers served as CEO until his death in April of 2020. Benz is still actively involved as a corporate officer, while Dr. Dorsey has returned to academia.
  • Our roots are in medical education software, and we’ve quickly expanded to develop applications for pharmaceutical companies, non-profit organizations, and other healthcare-related organizations. More recently, we’ve moved into online testing and training, Website design and development, and business application development.
  • DxR Development Group virtual patient software is used around the globe, particularly in Asia. Our partners — Chun Shin Limited and DxR Asia-Pacific — distribute DxR Clinician, DxR Nursing SELECT, Clinical Competency Exam, and VirtualPT Clinician in both English and Chinese. DxR Clinician is also available in Japanese.
  • DxR Development Group is a great place to work! About half of our staff has been with DxR for more than 15 years, serving our academic and business clients/customers. We’re also hiring a new generation of employees to help carry on DxR’s tradition of thoughtfully designed software, a client-focused development process, and excellent customer service.
