After almost 125 years, the chiropractic profession in the U.S. enjoys a sustained advertising and public-relations effort that is changing the way consumers, other health care providers and decision-makers think about chiropractic. Our PR machine is led by Dr. Sherry McAllister, a doctor of chiropractic who, while maintaining a full-time practice, is crisscrossing the country to share the truth about the effectiveness of chiropractic at every open venue.
