Dr. Stephanie Sullivan is a scientist and chiropractor whose work focuses on advancing human resilience and deciphering the mechanisms of action for chiropractic care. Dr. Sullivan is the associate vice president of research and director of the Dr. Sid E. Williams Center for Chiropractic Research (CCR) at Life University, where she works with her team and collaborators to advance the center's mission-driven research.
Dr. Sullivan earned her Doctor of Chiropractic degree from Life University and holds a Ph.D. in neuroscience from the Biomedical and Health Sciences Institute at the University of Georgia. Her professional background includes a career in banking and marketing before she decided to return to school for research and chiropractic studies. Leveraging her past expertise, Dr. Sullivan has worked to propel the CCR forward, conducting impactful research studies, and disseminating valuable information through various media channels, such as presentations, peer-reviewed publications, and open-access venues.
Dr. Sullivan's research currently focuses on brain-based and autonomic changes following chiropractic care. She is particularly interested in exploring the role of chiropractic care in fostering stress resilience among active duty and veteran military service members and first responders. Dr. Sullivan's research portfolio extends to developing the Well-being and Health Expression Evaluation List (WHEEL) and establishing a research-based learning healthcare community.
Outside of her research commitments and university support endeavors, Dr. Sullivan enjoys spending quality time with her family, participating in outdoor activities, and working with her husband on their farm in the foothills of the Blue Ridge Mountains.

Senior Clinical Research Liaison
Amber Jackson, D.C.
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.
