Hirsch, M.D. Internal Medicine 847/214-5780 "I am a Board certified internist, receiving my medical degree from the Chicago Medical School in North Chicago, Illinois and completing my internal medicine residency in 1991 at Kaiser Permanente Medical Center in Los Angeles, California. I am also certified by the American Academy of HIV Medicine as an HIV specialist. "The role of the patient-doctor partnership is key to the prevention, detection and treatment of diseases such as hypertension, diabetes and HIV. It is this partnership along with a comprehensive treatment plan that emphasizes patient education and close follow-up that will help save lives while preventing life changing complications.
