Our History

Midwest Occupational Medicine was founded in 1992 by George Dirkers, M.D., in Wood River, Illinois, after recognizing the need for quality medical care for local businesses and industries, originally serving the local refineries, power industries, and manufacturers. Midwest operated for five years out of a small office previously occupied by a marine supply company before expanding into their own building, which broke ground in 1997.

With the launch in 1992 of Midwest’s medical branch, Midwest Occupational Safety was also formed to supply local contractors with assistance in OSHA safety compliance and to supply needed safety personnel for industrial and construction jobs. Midwest’s medical branch and Midwest’s safety branch merged in 1996 into Midwest Occupational Medicine, LTD. 

Midwest Occupational Medicine steadily grew to serve surrounding steel and chemical plants, trucking firms, schools and municipalities, hospitals, nursing homes, and an ever-widening list of manufacturers. The injury management business continued to expand. In addition to full OSHA compliance exams, respirator and fit testing, Midwest Occupational Medicine added services such as DOT exams, full service drug testing, on-site evaluations, and much more.

Midwest continued to expand with temporary and permanent on-site staffing, including physician, nursing, EMT, and clerical staffing for industrial clients, supplying staffing for heavy manufacturing, chemical plants, food manufacturers, and others. 

Midwest Occupational Medicine began 24-hour physician on-call injury management when approached by clients with the need to deliver responsive, effective ways to maintain physician-to-physician contact on more serious injuries that required employees to be evaluated at outside facilities. This on-call service continues to grow as Midwest now services clients throughout the United States and abroad.


Midwest Occupational Medicine continues to grow, most proudly by word of mouth from one client to another.
