About Dennis Tyrrell
HI! I'm Dennis...
If you’re here, there’s probably something in your life you’d like to feel a little different.
I understand that more personally than you might expect.
I’ve been the guy trying to quit smoking. I know what it’s like to live in a body that doesn’t always cooperate. I’ve dealt with chronic pain, stress, uncertainty, and ha
why I created Impact Hypnosis
If you’ve lived with chronic or complex illness, you probably know what it feels like to leave an appointment wondering if anyone actually heard you.
I do too.
I’ve gone from doctor to doctor looking for answers, only to be told that my symptoms were anxiety and that I should consider therapy. As someone who had actually worked as a therapist, that was an interesting conversation.
Professionally, it felt condescending. Personally, it was dehumanizing and invalidating.
I live with a neurodivergent brain inside a hypermobile body. I experience autonomic dysfunction, chronic pain, sensory issues, and—because apparently my nervous system has a sense of humor—a great migraine every now and then.
I’m a Zebra too. And that matters when you come to see me.
You don't have to spend the first half of your appointment explaining what dysautonomia is. You don't have to convince me that a normal test doesn't mean you feel normal. You don't have to defend the research you've done, apologize for knowing your own body, or worry that every symptom you describe is going to be reduced to anxiety.
We get to start further down the road.
We can spend our time working on what brought you here: helping your nervous system settle, reducing some of the additional load you're carrying, and finding practical ways to help you feel and function better.
That's why I created Impact Hypnosis.
Sometimes it helps to work with someone who's already part of the herd.
A Little About Me
I spent much of my career helping people on some of the worst days of their lives—first as an Army medic and later during more than two decades in the fire service.
Then an accident and injury changed the direction of my own life.
Eventually, I had to leave public safety. What followed was something many people with chronic illness will recognize: years of adapting, searching for answers, seeing different providers, and learning how to live in a body that no longer followed the rules I was accustomed to.
Along the way, I learned that I have a connective-tissue disorder as well as a neurodivergent brain. Suddenly, a lot of things about my body, my brain, and even my past made considerably more sense.
My professional path changed too.
I earned a graduate degree in counseling and worked as a therapist for several years. But I became frustrated with a model that often asked people to spend more time talking about how bad they felt without necessarily helping them experience what feeling different was actually like.
I wanted something more tangible.
Because when your nervous system settles, things can look different. You can think more clearly. Decisions can feel easier. Your body can soften. The noise can quiet down. You get an opportunity to experience a different state instead of spending another hour talking about the one you don't want to be in.
That's what drew me to hypnosis.
I wanted people to be able to walk out of my office feeling better than when they walked in—not reaching for a box of tissues on the way out.
My own health also taught me how expensive simply trying to feel better can become. Specialists, appointments, therapies, medications, deductibles, copays—it adds up quickly, especially when you're already dealing with a condition that affects your ability to work and live normally.
That's another reason I created Impact Hypnosis differently.
No expensive programs. No large packages. No long-term commitment before you even know whether this helps you.
Impact is meant to be an accessible place where you can come in, let some of the load down, and give your nervous system an opportunity to recover.
Whether you're living with chronic illness, trying to finally leave smoking behind, or simply worn down by life, my philosophy is pretty simple:
You absolutely don't need to talk more about how you feel. You need an opportunity to feel different.

Frequently Asked Questions
Please reach us at dennis@tyrrellconsulting.com if you cannot find an answer to your question.
I use the term functional hypnotherapist because my focus is practical: helping you feel and function better in everyday life. Rather than spending an hour simply talking about what’s wrong, we use hypnosis to help create a tangible change in state and give your nervous system an opportunity to slow down, settle, and recover.
I have graduate training in counseling and previously worked as a therapist, but I no longer practice psychotherapy. My work today focuses on hypnosis, nervous system regulation, behavior change, and helping people improve their overall quality of life rather than providing traditional talk therapy.
Many hypnotists rely on a one-size-fits-all approach. They use the same scripts, the same recordings, and the same process regardless of who is sitting in front of them.
That's never made much sense to me.
Before opening Impact Hypnosis, I spent years working in behavioral health, helping people navigate substance abuse, anger management, domestic violence, and other challenges rooted in human behavior. That experience taught me that people are different, and effective change usually requires more than a generic script.
My approach combines hypnosis with principles from psychology, behavior change, communication, and practical real-world application. Every session is tailored to the person in front of me, their goals, and the challenges they're dealing with.
Yes. I live with chronic and complex health conditions myself, including hEDS, POTS, MCAS, Migraine, & FND. I know what it’s like to navigate specialists, manage unpredictable symptoms, research your own conditions, and be told that something happening in your body might simply be anxiety. You won't need to spend your session convincing me that your experience is real.
No. Impact Hypnosis is intentionally pay-as-you-go. There are no required packages, long-term programs, or large upfront commitments. Start with the service that fits what you need, experience it for yourself, and decide from there.
Impact Hypnosis is a private-pay practice and does not bill or accept health insurance.
Some hypnotherapy services may be eligible for reimbursement through your HSA or FSA. Smoking cessation programs generally qualify, while hypnotherapy related to a medical condition may require a Letter of Medical Necessity from your healthcare provider. Sessions used solely for general relaxation or wellness may not qualify.
Because every plan is different, check with your HSA/FSA administrator before booking if you plan to use those funds.
I’m happy to provide a detailed receipt for your session to support reimbursement when needed.
