What Graduates Are Saying
Former State Assistant Attorney General Reports His Results From Our Hypnotherapy Training
“I learned more powerful and effective techniques to facilitate growth and positive change at the Hypnotherapy Academy than during my entire psychology master’s program! Tim has masterfully integrated the best of the best of what truly works into his hypnotherapy certification course.
In three years at Georgetown University and another three years at the Institute of Transpersonal Psychology, I NEVER EXPERIENCED SUCH HIGH QUALITY TEACHING and such a useful curriculum as I have at the Academy.
I am a happy beneficiary: I reached very specific financial goals, and became a happier, more centered and enthusiastic person as a result of the course.”

"Attending the Hypnotherapy Academy of America Has Changed My Life."
In ten weeks, I learned more than I ever expected to. The knowledge of the instructors is unbeatable, and the experience they shared with us is priceless. I DIDN'T EXPECT TEN WEEKS OF TRAINING TO GO BY SO QUICKLY; I ENJOYED EVERY MINUTE, THUS IT FLEW BY. Not only that, every night after class I still continued wanting to learn, as the materials and information were so very interesting.
"Academy Directors, Tim and Angela Simmerman Sierra bring such a genuine love for hypnotherapy to their lectures and demonstrations. Although we were not in a classroom together, every day I could feel their love and presence with each new exciting topic we covered.
"Angela is a walking miracle, and I feel blessed to have met her and experienced her warmth. My hypnotherapy training would not be the same without her or Tim -- he truly loves being in the service of others and sharing that with his students.
"The course is designed in such a well-structured way; I can tell the instructors have polished the course curriculum over the years to be able to deliver the best education to the students who they truly value.
"If you're thinking of attending Hypnotherapy Academy of America, do it. Go and grow, as I did!
"No other hypnotherapy training comes close to the level of knowledge and experience you gain at the Hypnotherapy Academy of America. The hypnotherapy methodology that they teach is the only one that has been scientifically validated by National Institutes of Health-funded research. I am proud to have attended HAA and LEARNED FROM THE BEST IN THE INDUSTRY."

"Not only did we receive the best preparation in clinical and medical support hypnotherapy, but we also formed a community that will support us beyond graduation. The quality of education at HAA is rare and worth both the financial and time investment."
What Does Comprehensive Training Mean?
Comprehensive training goes beyond learning a few techniques. So, whether you are a beginner or want to add clinical hypnotherapy to an existing practice, this course is for you. Here is some of what comprehensive training means:
Understanding the science of mind and body
You’ll learn how hypnotherapy works on the neurological, emotional and behavioral levels.
Mastering multiple modalities
Gain exclusive training in Integral Hypnotherapy®, the proven multi-session system used in an NIH-funded clinical trial on hypnotherapy.
Not only will you learn methods to help people reach their goals in life, but we also teach you how to heal the underlying subconscious issue that leads to transformation.
Developing practical skills
Hands-on, supervised practice throughout the course ensures you're ready to help people with real-world problems upon graduation. For example, by day 3 of the training, you will be conducting hypnotherapy sessions while a teacher is there to provide you with support and one-on-one coaching.
Building professional excellence
Learn an ethical, client-centered, trauma-informed approach that fosters lasting success in hypnotherapy.
NO previous college credits are needed.

video testimonials
During the final day of Module 5 at the Hypnotherapy Academy of America, a new graduate with a Master’s degree in Education (M.Ed) and extensive teaching experience shared his perspective on the Academy’s accelerated training format.
He described HAA as the premier institution for anyone seeking thorough preparation for a successful career in hypnotherapy. He highlighted the program’s unique ability to teach students how to access and transform deeply rooted negative programming — an invaluable skillset that is not found anywhere else.
He thanked Tim and Ángela Simmerman-Sierra for cultivating a community of understanding where he felt genuinely accepted and personally enriched.
Fall 2024 Graduate Compares the Hypnotherapy Academy of America's Training with Others.
One of our graduates from the Fall 2024 class, a minister of Religious Science with years of experience in transformative training, shared his heartfelt testimony about his time at the Hypnotherapy Academy of America.
Having followed renowned leaders, he reflected on how none of his prior experiences matched the depth and impact of HAA’s hypnotherapy program.
He described the training as uniquely practical, profoundly transformative, and personalized in a way that not only prepares students to help others but also empowers them to undergo their own transformation during the process. This dual focus on personal and professional growth left a lasting impression on him.
He expressed deep gratitude to Tim Simmerman-Sierra for his exceptional teaching, noting that Tim models the very principles that he aspires to embody in both his personal and professional life. The graduate concluded by emphasizing how life-changing the experience at HAA had been for him, providing tools and insights that will guide him in his journey of service and growth.
Summer 2024, Graduate Compares the Hypnotherapy Academy of America’s Training to Other Courses She Attended in the Past.
A summer 2024 graduate of the Hypnotherapy Academy of America's training shares her reflections on the program during the final day of class. Having completed other hypnotherapy courses before attending HAA, she described how those previous courses left her feeling unprepared, as though something essential was missing.
She emphasizes that the value she received from HAA’s training is truly “unmatched.” At the same time, she remarks on how the Academy consistently over-delivers, providing not only the skills but also the confidence and depth of knowledge needed to succeed as a hypnotherapist.
She wholeheartedly recommends that anyone seeking hypnotherapy training choose HAA as their only option.
She speaks about her appreciation for Tim and Ángela Simmerman-Sierra, whom she sees as the torchbearers of a profound legacy carried by pioneers like Gil Boyne, Dick Sutphen, and Gerald Epstein. As an HAA graduate, she takes pride in knowing that her work is rooted in this lineage of wisdom and expertise.
A Journey from Pain to Healing: How Hypnotherapy Changed My Life.
Headache was more than just a discomfort for me—it was a shadow that followed me through every stage of life. Headaches were a part of my life for as long as I could remember. What started as a dull, tolerable pain during my high school years—something I brushed off as normal—slowly grew into something that affected every part of my life. Back then, it was manageable, just a 1–2 out of 10 on the pain scale—but it was always there, like an invisible weight.
Fast forward to my time working in Saudi Arabia, and the headaches became more intense and persistent. This triggered deep fear in me, so I sought medical help and underwent diagnostic tests. The results were shocking. My doctors found a small mass on my left temporal lobe. Thankfully, it didn’t require surgery, just yearly monitoring, but still, it was a heavy burden to carry.
When I moved to the United States in 2019, adjusting to a new life wasn’t easy, especially dealing with the impact of the COVID-19 pandemic, which only made things worse. But through it all, there was one constant source of strength: my now-husband, Seamus. His love, support, and belief in me truly saved my life.
Unfortunately, the headaches continued to worsen. At times, they reached a 10/10 pain level. I experienced vomiting, fainting, and strange episodes like smelling burning wood out of nowhere. A new MRI showed not only the old mass but multiple new lesions, and their cause was Unknown. I was referred to the headache clinic, but like many others, I had to wait years for an appointment.
My husband suggested hypnotherapy, so while I waited for the headache clinic appointment, I turned to hypnotherapy in April 2025, and it changed everything.
Hypnotherapy didn’t just help me manage the physical pain. It helped me heal deeply (emotionally, mentally, and spiritually). I discovered that my migraines were tied to unresolved trauma from my past. Hypnotherapy guided me to confront and release what I didn’t even realize I was holding inside. It didn’t just treat my physical symptoms, but transformed my entire being, uncovering some deep-rooted emotional traumas I had buried for years. Hypnotherapy helped me understand the “why” behind my thoughts, behaviors, and suffering. Through this type of hypnotherapy, I found not just relief, but true healing.
Most incredibly, my latest brain MRI showed "no new lesions, no inflammation and no new abnormalities". For the first time in many, many years, I am headache-free. I now wake up without fear and live each moment fully, cherishing time with my loved ones. I continue to listen to the personalized recordings Miss Ángela Simmerman-Sierra made for me, and I feel stronger, lighter, and more alive.
I want to express my deepest gratitude to Miss Ángela: your guidance, care, and spirit truly live up to your name. You are an angel!
And to my husband, Seamus: thank you for the constant love, for standing by me, and for leading me to healing.
To anyone reading this: Hypnotherapy is more than a treatment—it's a path to reclaiming your life. Don’t be afraid to try. You might just find the peace and freedom you’ve been searching for.
There is hope. There is healing. And yes, there is medical hypnotherapy.

May 8, 2026 - Update on Brain MRI
I’m incredibly grateful and happy to share that my latest brain MRI showed no abnormalities and no new lesions. This result means so much to me and gives me so much peace and hope moving forward.
What makes this even more amazing is that I am now completely free from migraine headaches. I have stopped taking pain medications, and my headache clinic has officially signed off on my care. It feels wonderful to finally live without the daily pain and worry.
I am thankful, relieved, and hopeful for the future. Truly an amazing blessing.
Thank you, Ángela, for helping me!
