@gldmontana, I do not live in WI, but I have several levels of evidence that the website Castle and Connolly lists the best doctors (referrals, my own selections, how C&C chooses who to list). There are several C&C-listed gastros in Kenosha. And, of course, you could travel farther. Chicago is closer than Aurora.

Here is the link for Racine, but if it doesn't hold, you can check for yourself on the C&C website:
