Hi,
My daughter's GI is Dr. David Rubin.(University of Chicago medial center).
He supports diet as supplementary to meds. ..
He mentioned he is very familiar with healing well forum....
Regarding appointment I am not sure...but you can ask for any possible cancellation so that they can plug you in...
We been there only once for the initial appointment.
He didn't insist on seeing every 3 months or so unless it's getting very uncontrollable.
All concerns are so far well handled thru email and phone with his fellow GI -an AWESOME extremely caring doc.
Dr.Stephen Hanuaer too is in the same hospital...Heard a lot of good things about him too....
