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.

In the winter of 2004, Dr. Dupuis was pleased to return to Maine where opened his practice, Back to Health Chiropractic, focusing on family care, athletic performance, injury prevention/treatment and rehabilitation.

Dr. Dupuis had the privilege to study Elite Sports Science at the United States Olympic training center in Lake Placid, New York.

Since the summer of 2007, Dr. Dupuis has functioned as Team Chiropractor for the Sanford Mainer’s Baseball Team, part of the New England College Baseball League.

Recently, Dr. Dupuis served as chiropractor for the United States Bobsled & Skeleton Teams at the United States Olympic Training Center in Lake Placid, New York & in Washington DC for the NCAA National Tae Kwon Do Championships.

He attended Bowling Green State University where he earned his bachelor’s degree in Exercise Science, completed strength and conditioning internships with the University of Findlay Football Team and at Massif Athletics, and played lacrosse.

Dr. Rob suffered a shoulder and neck injury that caused his arms to become numb and unable to do the tasks involved with the S.W.C.C. training program. It was not until after a medical discharge and a few visits to a chiropractor that his symptoms were resolved. After becoming frustrated with the allopathic model while serving in the military, he decided to become the change he wanted to see in the healthcare system by becoming a chiropractor.

In August of 2020 Dr. Rob graduated Cum Laude from Logan University in St. Louis, Missouri. While studying at Logan, Dr. Rob worked as a chiropractic assistant and tutored anatomy and neurology. He completed clinic rotations at the Montgomery Health Center treating students and patients from the surrounding community, the Cincinnati VA medical center treating those who served their country, and at Sugarcreek Chiropractic in Dayton, Ohio treating athletes and their families. Dr. Rob and his wife, Kassidy, moved to Maine following graduation to enjoy the mountains and ocean. While not in the office, you can find Dr. Rob at the Crossfit box, hiking, kayaking, skiing, or walking down the beach with his wife and their beagle, Kevin.
