The history of Dreyer Medical Clinic started in 1905 when Dr. John Dreyer opened up a medical practice in Aurora, IL. Gaining several more physicians over the next few decades and moving to larger office space, the Dreyer Medical Clinic finally got its name and permanent location on the west side of Aurora, IL in 1964. Over the years, it expanded its practice to other neighboring towns including Batavia, Yorkville, St. Charles, Hinckley, Oswego, and Plainfield. In 1996, Advocate purchased the Dreyer Medical Clinic. The name was changed to Advocate Dreyer in 2014 and then in 2017, its name was rebranded as simply Advocate Medical Group.
