Hi C.-
My son has seen Dr. Jody Caldwell at the Sadler Clinic in Conroe. In my son's case we have eliminated wheat, milk and soy and he is taking many vitamin/mineral supplements. It has taken us a long time to get the program going in our house so I can't comment on the success yet, but she is definitely more interested in nutritional and natural treatments than many doctors. I think calling and talking with her about her approach to see if it's anything that you have not already tried would be worthwhile. She is listed as a family practice physician, however as of the last time we saw her she was no longer handling routine care for patients and was focusing on her autism clinic work.

Good luck,
