Angela P. Simmerman Sierra, NLPT, CMS-CHt, FIBH

Angela experienced first hand the transformative power of hypnosis after a IMG_2064near fatal car accident in 1988 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.
