The first step is to make sure that a hypnotherapist is certified by a credible international body that confirms the validity of their professional training. Secondly, it is important to feel comfortable and to resonate with the therapist. The more trust there is, the more successful the process will be. If you have any doubts, Ellen suggests that you call the therapist before you make a booking and chat about what you would like to change. That will help you make up your mind.
