That's a pretty far distance... but yes, there is a great GI that I recommend there! I attended school at UW La Crosse and found an awesome GI at Gunderson Lutheran... Dr. Scott Rathgaber. I can't praise him enough.
I was admitted to the hospital (Gunderson) the week before Memorial Day of '06 because of a bad flare up. I didn't have one single doctor (there were many) because of the holiday and I believe many of them were on call. I chose to follow up with Dr. Rathgaber because when he came into my hospital room I told him I had a list of questions to ask. He pulled a chair up next to my bed and answered every single one of them clearly and without making me feel dumb or rushed.
Also, there have been times when I have sat in his office for half an hour just asking him questions or discussing different options or treatments with him. Never once have I felt rushed. Also, if I ever felt like I needed to get in to see him, I never waited more than 2 days for him to get me in. He is very accomodating.
So, it would be a long drive... but if your son is at Winona it might make a good excuse to visit! Good luck with whatever you choose!!
