Dr. Seth LaFlamme began his studies in the humanities, studying writing, literature and philosophy at the University of Maine. He brought these passions and priorities to his studies in Chiropractic at Life University where he earned the distinction of valedictorian of his graduating class.

Immediately upon entering practice, Dr. Seth entered a year-long postgraduate program in pediatrics and pregnancy via the International Chiropractic Pediatric Association, which emphasized the importance of development and childhood health and its influence on health outcomes in later life. From here, he began to see whole families, young and old, with very good results. Still, some patients obviously needed a deeper level of understanding to fully solve their case.

Convinced there was still more to providing the best quality patient care, Dr. Seth went on to complete postgraduate studies in Functional Neurology and became a board certified Chiropractic Neurologist via the American Chiropractic Neurology Board.

Ongoing studies in physiological integrity through Standard Process and Developing Minds University led to the discovery that a balanced function of brain, body and biochemistry are required to have vibrant, robust health and a joyful, energetic life.

This led Dr. Seth to co-found the 3B Synergy Health Systems, a program dedicated to achieving balance and optimal function to these three foundational pillars of health.

This is the guiding light for our practice to this day, achieving successful results for patients with a wide variety of problems, whether pain-based, neurological or developmental.
