The chiropractor's expertise includes the nervous, muscular and skeletal systems. Chiropractors are trained to (assess and) diagnose a condition which allows them to develop individualized treatment plans for patients to appropriately address a patient's condition according to their unique needs and age. The chiropractic approach, philosophy, art and science, focuses on supporting the body's inherent ability to maintain balance and heal itself. In other words, the chiropractor works with the body's inherent abilities to maintain health using primarily spinal manipulation without the use of medication or surgery.
