20 Years of Therapy, or 3 Sessions of Hypnosis?

I recently got an email from a client I helped with self-esteem and trust as related to dating and relationships. She thought she was going to need six sessions, but three ended up doing the trick.  Here's an excerpt from her message:

"The few hours I spent with you have done more for me than the last 20 years of trying different therapists and therapies." -Brandi Williams

I've actually received similar verbal feedback from two other clients recently. Hypnotherapy, when used effectively, works quickly.
