Need a doctor!!!!!

Anyone out there from Chicago who can give me the  name of a great GI in the western suburbs? I'd love to find someone who fully supports the idea that diet has a huge effect on crohn's.  I have a dairy intolerance that seems to cause my flare ups every time.  When I've told GI doctors about it in the past, they give you that look like whatever, here's some drugs!  I need my drugs but would like a doctor who supports the holistic approach too.  Thanks!!!
