Why Chiropractic Will Help You

It is proven that the main cause of back pain, neck pain, and many diseases is the misalignment of the spine. Dr. Duff and Dr. Natalie are the only chiropractors in Boulder that specializes in a form of chiropractic that creates visible changes in these misalignments along the entire length of the spinal column. These changes in posture relieve the tension and pressure on the spinal cord and nerves. When the proper nerve function is restored, the body can begin to heal itself. Over the years, Dr. Natalie and Dr. Duff have helped thousands of people gain relief from conditions like:

Real Reviews from Real Patients

Dr. Lyle, Dr. Duff, and their staff have created a warm, welcoming, “family” atmosphere where healing happens! Both my husband and I have had chronic, and occasionally acute, back pain for years. We saw chiropractors in the past but they were both painful and ineffective. Since our treatment began at Terry Chiropractic we are feeling, and moving, better than ever. We look forward to our visits and to the love and care we receive.

After one month of coming in for tractions and adjustments my headaches went away– and now after several months of traction with the spine, the curvature in my neck is back in a normal range.
- Caitlin

I have the pleasure of seeing Dr. Duff and Dr. Natalie on a regular basis. They are incredible doctors that have helped with not only my back problems but also my knee injury. They take the extra step to X-ray and make sure I am given the exact care I need. I highly recommend TCB for all of your health and wellness needs, and like they say, “to make 2020 your healthiest year yet.”
