Our Typical Patients:

Our Doctors have viewed and treated thousands of neck and head pain patients and sufficiently aided over 80%.

Headache Patient:

The patient possesses a history of mild to severe headaches that have not reacted in any prolonged way to other types of treatment. Most of these patients have tried some form of alternative treatment (chiropractic, naturopath, massage, etc.) but continue to have problems that significantly affect their lives. Many rely on medication that could have potentially dangerous side effects on the liver and kidneys. These patients often do not realize the impact that their pain has on family and work.

Neck Pain Patient:

Has a background of neck pain brought on by some form of trauma, or by a long series or micro trauma (sitting at a desk, computer work, dental hygienist work, etc.) The patient will constantly feel a need to rub their neck, or may be in the habit of popping, snapping or cracking their necks to find relief. Neck pain typically affects sleep and mood.

Whiplash/Job Injury Patient:

Has a background of a recent or long-ago neck/upper back injury that has not healed on its own or with treatment. The Journal of Whiplash and Related Disorders recently reported that 84% of these patients see complete or near complete resolution of pain after undergoing Atlas Orthogonal Treatment.

Scoliosis Patient:

Our Scoliosis patients are of all ages. Contemporary understanding of the Atlas misalignments and their connection to Scoliosis and Kyphosis has prompted the combination of Scoliosis treatment and Atlas Orthogonal adjustments.
