The lady from http://www.digestivewellness.com/webpage.asp?id=43 has recovered from crohn's, and Lucy from Lucy's Kitchen Shop has recovered from ulcerative colitis. All of the SCD cookbook authors suffered from some intestinal ailment (crohn's, UC, celiac, etc.) and have recovered. You could look them up to find their stories.
Like EMom said, the BTVC and pecanbread groups are also good places to look for success stories.
I don't know that anyone ever achieves "perfect" health though. That's a pretty strong order. For instance, stress can send many crohn's people into a flair. Some people on BTVC have mentioned that they needed to learn to do things like meditation in addition to the diet to keep their crohn's from rearing up under high stress situations.
I'm doing pretty well on SCD, but still take Pentasa. I also want to add in LDN, because the one thing SCD hasn't helped me with is fatigue. However, I will stick with the diet for many years (probably forever) because it has helped so many of my problems
