Flexx Chiropractic

Our Story

In 1971 Saum Chiropractic Clinic began providing the highest quality chiropractic care for Columbus, MS, and the Golden Triangle. Dr. Shana Thomas began working with Saum Chiropractic Clinic in 2006 as an associate doctor. After Dr. Saum’s retirement in 2016, Dr. Thomas purchased the practice, and in 2018 Saum Chiropractic Clinic was rebranded as Flexx Chiropractic. The new brand carries with it a mission to change the way people think about healthcare. Chiropractic care is excellent preventive care and allows the body to heal itself without the use of drugs or surgery. Flexx Chiropractic offers a unique and personal approach not only to help people get out of pain, but to move them to an opportunity where they can improve their quality of life. Flexx Chiropractic currently serves the Golden Triangle from its Columbus, MS, location led by Dr. Shana Thomas and her associate Dr. Dustin Knickrehm.
