International Chiropractors Association

Doctors of chiropractic from around the United States have answered the call to participate in a new initiative aimed at supporting America’s newest returning veterans with immediate access to chiropractic services, in addition to the limited programs officially available through the US Department of Defense. Out of a desire to serve and to fill in a vitally important health care gap, ICA doctors around the nation have extended an offer of care for one full year for any US military veteran returning from overseas deployment in Afghanistan and Iraq, at no charge. The concept was developed by ICA’s Southern Regional Director Dr. R.J. Kelly, who had initiated such a program in his own personal practice, with very positive results among veterans.
