Chiropractor John Negley D.C.
John William Negley, DC is a Nashville native, growing up in Franklin, Tennessee after he moved here with his family in 1997. He attended and graduated from Franklin High school in 2008. In Chicago he received his undergraduate degree in Applied Science, Pre-Medicine from Wheaton College in 2013.
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 Health and looks forward to helping the greater Nashville community!

Katrina Giuliano Hausmann - Acquisitions Director
Katrina is a Nashville native from Dickson, TN. She married Dr. Hausmann on April of 2017. She received a Master’s in Nutrition and Exercise Physiology from Lipscomb University after completing her B.S. in Exercise Science at Tennessee Tech University. She has over 10 years of experience in the exercise industry and 5 years of personal health coaching experience as well.
At a younger age, she saw her brother struggle with his health due to an autoimmune disease. A long road of medical treatments and procedures provided him with no improvement. It wasn’t until he was introduced to proper nutrition and exercise that he radically healed and transformed his health. Doctors were astonished! 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. She is excited to share her commitment to health with everyone here at Stronghold, and her compassion and drive makes her a wonderful addition to our team.
