Dr. Amber Jackson, known as Dr. Jackson, is a passionate chiropractor dedicated to providing exceptional care to her patients. With a background in fashion and retail management, Dr. Jackson's journey to chiropractic medicine was inspired by her personal experiences as a student athlete and her commitment to helping others heal and thrive. Dr. Jackson's career path took an unexpected turn during her time as a student athlete at Alabama State University. While playing volleyball, she suffered a back injury that led to multiple disc protrusions in her lumbar spine. This injury forced her to reconsider her dream of becoming an orthopedic surgeon. After soul- searching and self-reflection, Dr. Jackson had vision that led her to discover the field of chiropractic medicine. Since then, she has been unwavering in her dedication to helpingpatients find healing and relief.
