Doctors of Chiropractic, otherwise known as chiropractors, are individuals who have undergone rigorous academic, medical and clinical training in the musculoskeletal and nervous systems. In the areas of anatomy, physiology and rehabilitation, Doctors of Chiropractic have received extensive education and stringent instruction which often surpasses that received by medical doctors and physical therapists. As experts in the healing sciences, chiropractors approach physical health and well-being from a drug-free standpoint and operate from a highly-trained “hands-on” approach. In assessing the patient’s overall health, Doctors of Chiropractic utilize extensive knowledge in the fields of nutrition and diet; therapeutic and rehabilitative exercises as well as counseling regarding lifestyle. According to the American Chiropractic Association (ACA), over 27 million individuals of all ages visit a chiropractor each year. As of December 2013, the Council on Chiropractic Education (CCE) (the agency the U.S. Department of Education certified to accredit doctoral programs) reported that there are 18 chiropractic doctoral graduate education programs in the United States.
