I started reading clinical psychology books at age 15, literally a book a month. I got my degree in psychology in college. And I've read hundreds of psychology books since college. Hypnotherapy was just the next step up.
Although I'm no MD, I also study neurology, physiology, pathology and cytology in order to help me understand how the mind and body operates.
I'm a "direct medical hypnotist" in that I help people with severe issues. In my first several years, I worked with 3 actual medical doctors who incorporated "direct" hypnosis techniques for burn patients, cancer patients, PTSD patients and those in extreme physical or emotional pain.
I continued to expand my knowledge of the power of the mind by spending years studying, practicing and helping others using the following:
√ Cognitive Behavioral Therapy (CBT)
√ Progressive Relaxation Techniques
√ Autogenic Training Techniques
√ Guided Meditation Techniques
√ Visualization Techniques
√ Stress Management Techniques
√ Pain Free Childbirth Techniques
I also offer stage hypnosis in regards to helping Corporations because of my knowledge in Medicine, Stress Management and Focusing to Achieve Goals Techniques.
As for "comedy" stage hypnosis for schools and parties, anyone with half a brain and a very limited knowledge of hypnosis can entertain people. It takes very little knowledge of hypnosis to say "relax this muscle, that muscle, sleep, now dance like a drunken monkey."
