Dr. Marc Dupuis

Board Certified Chiropractic Sports Physician
Clinic Director of Back to Health Chiropractic PC

Dr. Marc Dupuis, originally from southern Connecticut, relocated with his family to Sanford, Maine as a youth where he attended local schools and graduated from Sanford High School. Dr. Dupuis completed his undergraduate studies at the University of Maine at Orono, where he received a bachelor’s degree in Biology. Following his graduation from UMaine, he realized his passion was to work with people and health care seemed like a natural fit to combine his background in science and research while helping people achieve optimum health. While preparing to attend graduate school in an allopathic medical program, Dr. Dupuis gained hands on experience with patient care while working as an Emergency Medical Technician. It was during this time as an EMT that he developed back pain as a result of repetitive lifting of patients. Dr. Dupuis decided to see his family’s chiropractor and after one visit, he felt significant relief! Perhaps what was more surprising was that after a few visits he noticed improvements in his running and biking. This experience prompted Dr. Dupuis to shift his academic plans and attend graduate school at New York Chiropractic College. The Chiropractic Philosophy of helping individuals achieve health naturally without the use of drugs or surgery and its role in performance improvement of athletes resonated well with Dr. Dupuis’ own views on health.

In 2003, Dr. Dupuis graduated Magna Cum Laude from New York Chiropractic College, in Seneca Falls, New York.

Dr. Dupuis completed his intership at the Camp Geiger School of Infantry & the Camp LeJune Naval Hosptial, both located within the Camp LeJune United States Marine Base, Jacksonville, NC.
