Dr. Hanauer is the top researcher in Crohn's and Colitis in the country I highly recommend him or Dr. David Rubin who works with him at the University of Chicago. Google both of them and they are all over the net. I go to Dr. Rubin myself and he goes all over the country teaching and educating both patients and physcians on the latest and greatest treatment options. You can also see Dr. Rubin at www.crohnsandme.com
Again, Hanauer is the top in the field and you cannot go wrong with him! Here's his bio from the University of Chicago Medical Center's webpage:
Dr. Stephen Hanauer is a world leader in the treatment of inflammatory bowel diseases (IBD).
He is the past chair of the Immunology, Microbiology and Inflammatory Bowel Disease Section of the American Gastroenterological Association (AGA). Dr. Hanauer is the recipient of the AGA's Fiterman Award for Clinical Research.
He previously served as a member and chair of the Food and Drug Administration (FDA) Gastrointestinal Drugs Advisory Committee and currently chairs the International Organization for Inflammatory Bowel Disease.
Dr. Hanauer is a member of the Crohn's and Colitis Foundation of America's National Scientific Advisory Committee.
Dr. Hanauer led a team of researchers who discovered a maintenance therapy for Crohn's disease.
In 2001, a team of University of Chicago physicians along with researchers from the University of Michigan identified the first gene that increases susceptibility to Crohn's disease.
Good Luck you have been through so much already you will be in my thoughts-
