Testimonials from former students:

From students in my 2015 Intuition/Spirituality course:
“As always Katherine’s class was excellent. Informative and creative beyond expectations.”


“A great listener; aware, discerning, insightful, joyful.”


“Your style is unique in that you have a way of ‘becoming one’ with the students you teach. You integrate yourself so well that one feels they are listening and responding to a good friend who knows and understands their problems. You begin helping them overcome obstacles, and reach beyond themselves as soon as you start talking. Your unshakable self confidence envelops the student creating the necessary atmosphere in which to grow and learn. As I observed this remarkable teaching skill, respect and admiration have only grown since I first sat in your class.” Mary A. Caldwell, CHT


“If you look up the word ‘professionalism’ in the dictionary, you will see Katherine Zimmerman’s picture. Katherine conducts her hypnotherapy training courses with great integrity, passion and commitment. She is as excited to witness the growth in her students’ professional skills and personal development as the students themselves. From the first time I met Katherine, I knew she would be the right teacher from whom to obtain my hypnotherapy certification training. Katherine learned from the best: her teachers comprise a ‘Who’s Who’ of the top names in modern Hypnotherapy. In addition to her wealth of knowledge and first-hand experience gleaned from many years in private practice, Katherine’s genuine warmth and natural wit make her hypnotherapy training a truly entrancing and life-transforming experience.”
Nancy Tracy, CHT


“Katherine is a wonderful teacher and her course is outstanding at every level. Her teaching style is hands on and the classes are very participatory. Students begin practicing hypnosis during the very first weekend class. Katherine’s style is to discuss a technique (and she teaches many), then demonstrate it with one of the students. After that, the students begin practicing it on each other, under her close observation. Within a week of my first class, I was successfully using the techniques she taught us with my own clients. The results have been nothing short of remarkable. What I thought would be just another tool in my therapeutic toolbox, has become one of my primary tools. I wholeheartedly recommend Katherine and The California Hypnotherapy Academy to anyone interested in learning more about hypnosis and hypnotherapy.” Ray Brown, PhD, LMFT, CCHT
