Imaging taken before the first correction allow us to “see” the exact position of your spine. Careful analysis reveals a precise correction formula used to restore your spine to its proper alignment.

NUCCA (pronounced ‘new-ka’) stands for the National Upper Cervical Chiropractic Association and is a very
gentle chiropractic technique that involves absolutely no “popping” or “twisting” of the neck or back. The precision of the adjustment allows us to work smarter, not harder. You’ll be amazed at how gentle and precise the adjustment is!

By correcting the entire spine and not just the problem areas, the body can stay corrected for longer periods,
allowing for better recovery.

Our Patients
Are Saying

Dr. Harrison’s clinic offers a professional and friendly environment in addition to a treatment that has yielded amazing results. The NUCCA concept is simple yet effective; the adjustment is like nothing ever experienced in my 20 years of chiropractic experience as a patient. Highly recommend a visit.

Bill D.

Dr. Allen is an incredible NUCCA chiropractor and I cannot recommend him highly enough. My teen children and I are patients, and he never fails to "put our heads on straight", whether we are suffering from growing pains, concussions or aging, we always feel better after our visits!

My appointments with Dr. Harrison have been helpful and informative. The encounters with him have given me more hope that I can get realigned and stay that way for my own comfort! I highly recommend Dr. Harrison

I was experiencing a lot of lower back and hip pain before I found the balanced atlas. The fact that my treatment began with x-rays meant a lot to me. I was able to see just where my problems were, which I feel is very important. Over a pretty short time (3 visits about a week or two apart) I have felt better, and also been able to see my progress. I love Dr. Harrison’s demeanor and style compared to others. I have already recommended the balanced atlas to friends and acquaintances that are having issues like mine.
