Has anyone been to a lecture by John and his wife Betsy Hicks. They are the parents of an autistic child. Betsy is the mother and is a nutritionist and John a pediatrician that met her son at age 8. they speak on everything from vaccinations to the gluten free diet thing, heavy metals, calcium, all kinds of testing, etc... This was my 1rst seminar, (so some of the stuff went over my head) me and my husband have attended and walked away with so much info. I was actually crying on the way home cuz I felt a little to overwhelmed. but today w/ things a bit more in percpetive, I feel it was a wonderful lecture nad cant wait for them to come back! You can ask them anything! They have a web site and are based out of Wisconsin (?).
