There are Stage Hypnotists who perform shows, Hypnotherapists who perform hypnotherapy (helping people with many different things the most common of which are quitting smoking and losing weight, however people see hypnotherapists for many other issues they want help resolving) and Clinical Hypnotherapists who also see people for hypnotherapy and have more training than Hypnotherapists.
You may hear other titles like Master Hypnotist, Master Stage Hypnotist, Master Hypnotherapist, however they are just other variations of names for the other three. All of these hypnotists may or may not perform stage shows and/or hypnotherapy. It is important to note that a Stage Hypnotist and/or Hypnotist performing a seminar such as quit smoking or weight loss may not be a Hypnotherapist. Check their credentials. I’m personally a Stage Hypnotist and Clinical Hypnotherapist and member of the American Council of Hypnotist Examiners. In addition, the council has also given me a Certified Hypnotherapy Instructor certification as I also teach Stage Hypnosis.
