Angela P. Simmerman Sierra, NLPT, CMS-CHt, FIBH
Director (and TT, our school mascot)
Angela experienced first hand the transformative power of hypnotherapy after a near-fatal car accident in 1998 in which her skull was crushed. Her attending physician, one of the top neurosurgeons in the country, believing she was about to die, sent her home blinded and semi-conscious without any hope. Soon after, her family found a new neurosurgeon, who also used hypnosis and guided imagery. Without surgery or medication, he helped Angela regain her will to live. Within months her sight returned, she could walk again, and not long after was fully recovered. As a Certified Medical Support Clinical Hypnotherapist, Angela is passing on to others the techniques that helped her regain her eyesight and heal. She has been a Director, an instructor, and practical skills coach since 2008. She is one of our bilingual practitioners, working in English and Spanish. Angela is also the Academy’s Certified NeuroLinguistic Programming Instructor. She is a graduate of Robert Dilts’ NLP University, where she completed both her Master Practitioner Training and her NLP Instructor Training. More info about Angela…

“This has been an experience of a lifetime. It was so much more than I had imagined and so much more than I had hoped for. The teaching of Tim Simmerman-Sierra goes beyond just information. His teaching style & the “fun” he brings with it are without words. A master comes to mind. Angela is a master at hypnotherapy and she too has a “magical” quality & gift. Her warmth & attention to her students is obvious in her just being. Together they have created an environment of learning & love that is contagious – I will never forget my time here at the Academy. It has not only taught me to be a first-class hypnotherapist, but also a first-class person.”
Bonnie Bangert, Colorado

“My time at the Academy has far exceeded my expectations. The immersion format has given me a direct experience of the power of the mind vs. merely an understanding of intellectual concepts. Tim’s vast amount of knowledge, his philosophy of service and his masterful way of teaching and sharing his experiences make this program unsurpassed. The offering of private sessions, the availability and sincere service of the coaches and the overall spirit of love and connection here have made this such a comprehensive experience that no one could leave unchanged!
Sandy Fox, Florida
“I had the pleasure of the most excellent training here from Tim and Angela and the talented coaches. Each person’s life story and strengths added something exquisite to my learning. I have been a teacher myself for 8 years and I myself felt so supported and well-trained – there is truly so much high standard, thought, care, direction and science that has gone into this curriculum and its presentation. High-quality teaching and education of the highest emotional and scientific standards has been outstandingly exemplified and shared here by my instructors. Thank you.
Lopa Visaveliya, New Jersey

Jane Darnell-Miller, MA, Alaska
“My experience at the Academy was life-changing. I learned more about myself, made really close friends and learned a wonderful skill of hypnosis that will allow me to help others heal. I also was introduced to Dr. Rosenberg’s NVC which made a huge difference in my communications. I loved Tim & Angela’s wonderful attitude and appreciate all of their teachings. Also thankful for Dr. Sapien. Many, many thanks and love to everyone in Academy.”
