Services
Migraine Relief
We assess patients whose chronic headaches have not responded to medication and identify misalignments of the atlas and axis. The Blair upper cervical adjustment gently restores proper alignment, eliminating the source of brainstem irritation. Clients experience reduced migraine frequency and intensity without drugs or invasive procedures.
Vertigo Treatment
We evaluate individuals suffering from vertigo or Menieres disease when conventional ear treatments fail. Precise 3D imaging maps the upper cervical spine, and a customized byhand adjustment relieves brainstem pressure. Patients report lasting balance improvement and diminished dizziness without medication.
Neck Pain Correction
We treat neck pain and whiplash by targeting the upper cervical vertebrae that absorb sudden head movement. Using a gentle, byhand correction based on each patients imaging, we restore structural integrity without cracking or medication. The result is lasting neck function and reduced muscle tension.
Low Back Pain Relief
We address sciatica and low back pain that originate from misalignment at the top of the spine. After precise imaging, a tailored upper cervical adjustment releases nerve compression and reestablishes proper neural communication. Clients experience decreased leg pain and improved mobility without surgery.
Concussion Care
We help patients with postconcussion syndrome by correcting upper cervical misalignments that keep brainstem interference active. The Blair technique uses gentle, byhand adjustments following detailed imaging, allowing the nervous system to heal naturally. Patients report faster symptom resolution and return to daily activities.

I've been visiting Health First since February after experiencing neck, shoulder, and back problems resulting from a car crash. Dr. Santos conducted a thorough evaluation and convincingly explained her results and conclusions in uncomplicated terms. She designed a plan to address my issues which consisted primarily of chiropractic sessions with her and ligament therapy with Stephen Wadsworth. All of the staff at Health First are knowledgeable, skilled, and friendly. As a consequence of my treatment, I'm hopeful for a full recovery and I'm armed with tools to proactively address potential issues going forward. I highly recommend Health First Chiropractic.

I really liked that before starting any treatment Dr. Santos does an x-ray, and a lot of different tests, then the doctor analyzes the situation, explained me precisely what's going on with my body and only after that sets the vertebrae. Everyone in this clinic is very attentive, kind, caring and good professional. The clinic is very cozy, the atmosphere is relaxed with great music. If you have pain in your body, I recommend you First Health Chiropractic

A huge kudo for Dr. Santos! She has done wonders for my neck and shoulder pain by using a technique that focuses on very specific and minimally invasive adjustments. I particularly appreciate her very thoughtful approach and all the information she provides along the way. I feel like I have a partner focused on helping me optimize my overall well-being. Recommend to anyone looking for a truly customer-centric chiropractor.
