Dr. David Marquis, DC DACBN

Dr. David Marquis, DC DACBN Dr. Marquis is a Functional Medicine doctor who goes beyond symptom management medicine.

How many people do you know that think they have some form of "ADD or Aspergers", or just get "Foggy in the Brain" and are forgetful of names and places or those who stumble or trip a lot. These are all subtle signs of a Brain Imbalance that affect health in ways that will totally surprise you. Patients who have unrecognized neurological symptoms due to an imbalance between their left and right brain hemispheres need help and medication isn't always the solution. Drugs treat the hemispheres equally, where as Brain Based Therapy can treat a specific area in the brain; effectively helping the patient recover from symptoms and conditions caused when the brain is imbalanced. These unique therapies when combined with proper fuel delivery (metabolism) allow patients to succeed in overcoming their blocks to optimal health. After a complete evaluation which often includes full labs and physical exam along with history to determine the actual cause of complaints Dr. Marquis will implement an equally comprehensive treatment plan. He will leave no stone unturned to assist his patients in their recovery.

Stop guessing — start testing. 🧪✨
Your symptoms are signals, not random. Functional lab testing dives deep into what’s really going on inside your body:

🔥 Inflammation markers – reveal hidden stress, gut issues, or chronic disease risks
💥 Hormones – help uncover imbalances affecting mood, sleep, energy, and weight
🧬 Insulin – key to understanding blood sugar, cravings, and metabolic health
🥑 Fatty acids – show if your cells are fueled or inflamed

The last slide shows what a typical Dr. thinks of our lab order list. This isn’t just data — it’s a roadmap to healing. 🔍💫
