Phases of Care at Chiropractic Works
A 3-Step Process

Depending on your condition, your care will follow a three-step model.

Once it’s fixed, you don’t want it to happen again, so we work with you to strengthen the parts of your body that caused the problem in the first place. Strengthening those muscles essentially retrains them to do what they ought to be doing.
