Dr. John Negley, DC

Associate Doctor

He was introduced to Chiropractic in 7th grade when his mother suffered from a condition called Trigeminal Neuralgia, an issue with the 5th cranial nerve that provides motor and sensory function to the face. It is termed a “suicide disease” due to the unrelenting and excruciating pain caused to the person afflicted, making the individual feel as there is no other alternative. After six months of being told nothing could be done other than surgery, Dr. John found a website introducing him to the alternative methods of chiropractic. Within two visits to a chiropractor, her pain was in complete remission! Once Dr. John saw the powerful life-changing effects of chiropractic care, he was accepted into Fountainhead of Chiropractic, Palmer College of Chiropractic, in Davenport, Iowa. While in attendance at Palmer, he completed his graduate degree as a Doctor of Chiropractic, learning from some of the best in the profession. He was trained in the science, philosophy, and art of Chiropractic, spending three and a half years working on technique and gaining the knowledge to provide the best care possible for his patients. He returned home to Nashville to help provide this city the same life-changing care that was given to his family. Giving instruction, providing education, as well as restoring proper alignment to the body so that it can function at optimum capability—these are some of his greatest passions. He is beyond excited to be joining the amazing team here at Stronghold Chiropractic and looks forward to helping the greater Nashville community!

Seeing him fully recovered and healed, Katrina became extremely passionate and driven to help others achieve health and healing through nutrition and holistic methods. When realizing that chiropractic care can help get to the cause of so many diseases people deal with, and how these simple lifestyle changes could have prevented years and years of unnecessary medications and hospitalizations, Katrina decided to dedicate her life to teaching the world about proper nutrition, exercise, chiropractic care, and living a healthy lifestyle.
