Years of Migraines. Medications That Mask It.
What if the Cause is in Your Neck?
A subtle misalignment at the top of the spine can disrupt the brainstem and trigger chronic migraine patterns. Dr. Stenberg corrects it with precision imaging and zero forceful manipulation.

You Have Tried Everything. The Headaches Keep Coming Back.
Chronic migraines have a way of quietly taking over your life. Not all at once, but gradually, until canceling plans feels normal, carrying medication everywhere feels necessary, and the idea of a pain-free week feels like a distant memory.
-
You cancel plans because you cannot predict when the next one will hit
-
You miss work, lose days, and manage around the pain instead of solving it
-
Medication dulls the edge but never breaks the cycle
-
You have seen neurologists, tried PT, tried general chiropractic, and still end up back at square one
Most migraine treatments are aimed at managing symptoms: medication to blunt the pain, injections to reduce frequency, therapy to manage triggers. These approaches have value. But they share a common limitation.
If the structural cause of the migraine is never corrected, symptom management is all that is possible. The headaches are not the problem. They are the signal.
For a significant number of chronic migraine sufferers, that structural cause begins at a place most treatments never examine closely: the very top of the cervical spine.



Is Your Neck The Problem?
At Zenith Upper Cervical Chiropractic, every evaluation includes the NeckCare System, a clinical-grade assessment that objectively measures how your cervical spine is moving, sensing position, and coordinating with your nervous system.
Results are displayed as visual reports compared against healthy norms, so you can see exactly where deficits exist and track real progress over time.

A Small Bone. A Big Consequence When it is Off.
At the very top of your spine sits the Atlas, the first cervical vertebra. It is the bone your skull rests on, and it surrounds and protects the brainstem, the most critical part of your central nervous system.
When the Atlas shifts even slightly out of its correct position, often from a car accident, a childhood fall, whiplash, or a sports injury years or decades earlier, it creates persistent irritation at the brainstem level. The nervous system responds with tension, compensation, and disrupted communication throughout the head and neck.
Over time, that neurological interference can contribute to a predictable pattern of symptoms.

Pressure at the base of the skull

Neck stiffness alongside headaches

Sensitivity to light or sound

Headaches that begin in the neck
The challenge is that these misalignments are subtle. They rarely appear on standard imaging and are almost never addressed by general chiropractic protocols. They require a specialist with specific training and specific equipment to find them.


Precise. Gentle. No Cracking, No Exceptions.
Dr. Stenberg uses the Blair Upper Cervical Technique, a highly specialized method that focuses exclusively on correcting the exact angle of an Atlas misalignment. It is one of the most precise and gentle forms of chiropractic care that exists.
Before any correction is made, specialized cone-beam 3D imaging maps the precise geometry of your Atlas joint. Because no two spines are shaped the same way, the correction is calculated specifically for your anatomy, not a generalized protocol applied to every patient.
The adjustment itself is remarkably gentle. There is no rotation of the neck, no high-velocity thrust, no audible pop. Most patients are genuinely surprised by how subtle it feels, especially those who spent years avoiding chiropractic care out of fear.
For many patients, once the Atlas is corrected and the nervous system begins to settle, migraine frequency and intensity start to decrease naturally over time. The body can heal when the interference is removed.
No Cracking
The adjustment makes no sound and requires no forceful thrust
No Twisting
Your neck is never rotated or torqued during treatment
No Guesswork
3D imaging maps your unique anatomy before anything is touched
No Frequent Visits
Our goal is changes that last, not a dependency on weekly appointments

Patients Drive From Across Colorado to See Dr. Stenberg. Here is Why.
The Blair Upper Cervical technique is not taught in standard chiropractic programs. It requires a separate, intensive post-graduate certification that only a small number of doctors pursue. In the entire state of Colorado, only 4 doctors hold this credential.
Dr. Stenberg is one of them. His patients come from Denver, Colorado Springs, Fort Collins, Pueblo, and beyond, many of them having spent years cycling through other providers without resolution.
This is not a general practice that offers upper cervical as one option among many. It is the singular focus of Zenith Upper Cervical Chiropractic, and it is the only thing Dr. Stenberg does.
