Glen Holton’s story:
On Anxiety – “Two years later I called to set another appointment with Shawn. I was having serious business difficulties. When I stepped into the waiting room, his wife, Zelda, took one look at my eyes and interrupted Shawn m’ the middle of a session.

He was so successful removing my fear and pain I didn’t want to come out of the hypnotic trance. I finally felt safe.”
