Advocate Dreyer Strengthens Ties to Advocate Medical Group

New name outside, same great care inside

AURORA - Advocate Dreyer will begin to be branded as Advocate Medical Group (AMG) on January 1, 2017. Dreyer has been affiliated with Advocate since 1996. Over the years that relationship has evolved – most recently represented by the transition in name from ‘Dreyer Medical Clinic’ to ‘Advocate Dreyer’ in 2014.

AMG is a physician-led and governed group comprised of approximately 1,500 clinicians representing more than 50 specialties. It is the largest physician group in Illinois, with more than 300 primary care and specialty outpatient sites throughout Chicagoland and Bloomington-Normal.
