sunrise,
If you contact NGH at
www.ngh.net and ask them for the Hypnotherapists in your area, this would be a wonderful start. Ask them specifically for someone trained in "Parts Therapy". These people will have the training you are looking for.
Everyone concentrates on a single thought through out the day. They call it day dreaming, zoning out, watching tv, reading a book, driving. As well as meditation is hypnosis, guided imagery is hypnosis, and the mental side of yoga is hypnosis. Pretty much everyone uses hypnosis EVERYDAY.
