If I were in your situation, I would probably find a WLS surgeon and then use them as a reference for a good GP. My surgeon is awesome...Dr. Thomas Chua in Milwaukee.
I live 2.5+ hours from Milwaukee, and this winter when I was needing some bladder resuspension done I wasn't sure I wanted to use the doctors from around where I live. I made an appt with Dr. Chua and discussed who he would suggest I go with. Unfortunately my insurance didn't cover the docs he suggested, but they did cover my appt with Dr. Chua as a follow up.
I hope your relocation goes well. I enjoy Milwaukee, having lived there until I was 30. Now 20 years later, I really miss it and wish we'd move back or at least closer again!
