I joined this site because I watched a video about John Chang and was interested in trying to locate him. I have a son that has Apraxia and cannot speak very well at the age of nine. I have always felt this was some sort of energy block. I would love to have somebody of the caliber of John Chang do some body work on my son. I realize running him down is an issue for many. Is there any body else that is highly recommended? Thank you!
