looking for pediatrician Chicago

Hi,
I am looking for a pediatrician for my two small children. Currently I am going to Hammond Indiana for their doctor and am not very happy with the condition of the clinic. I live in Chicago on the border of Indiana my zip is 60617. I can get to Hammond, Whiting, Munster and South East Chicago with just about a 10 minute drive. If you have any info that would help I would really appreciate it. By the way I live in Chicago near the Hegewisch area if anyone is familiar with that their zip is 60633.
Thanks
Jessica
