K.N.
I had my first child at Elmhurst and my second child at CDH. I loved my doctors at Elmhurst (I used RPW like the reply below), however I didn't like my experience at Elmhurst Hospital. I ended up taking my daughter to CDH a week after she was born and the NICU was awesome. The doctors were great, the nurses were great. Much better than the experience at Elmhurst. Because of that, I switched to CDH and used the doctors at DuPage Medical Group for my second child and had no issues with them. The whole experience at CDH was much better.
Good Luck :)
