At Atlas Chiropractic Center, Doctor of Chiropractic Justin Keffer plies his healing trade to the uppermost tip of the spine. Here, the free-floating atlas vertebra allows the head to swivel in all directions when checking a room for radio-controlled helicopters. But since it's not attached, the atlas is more likely to slide out of position and disrupt brain-body communication, leading to a host of potential health problems. Dr. Keffer nudges this disc into healthier positions in order to correct a range of ailments, from sore necks and headaches to digestive issues.
