Pathways to Health Functional Medicine

Metabolic ∙ Neurology ∙ Structural

Your Guide to Optimal Whole Health.


David M. Marquis, DC, DACBN

For over 25 years, Dr. David Marquis has assisted thousands of patients to find solutions to acute and chronic conditions without the use of or with minimal use of drugs or surgery. Through a metabolic and neurological approach to a patient’s health conditions, not only can the causes be determined, but the patient can learn how to manage their own health and often without medication. This is the underlying goal of care in Dr. Marquis’s office. Finding solutions and empowering patients to take their health back and become nondependent on the broken insurance-driven medical paradigm that plagues our country today.

When working with patients, it is often identified that their real problem is a result of an unrecognized neurometabolic issue. This means that they may have metabolic dysfunction such as blood sugar imbalances, autoimmune conditions, anemias, food sensitivities, latent infections, or simple nutritional imbalances which are complicating normal metabolism.

Functional Medicine

Functional medicine determines how and why illness occurs and restores health by addressing the root causes of disease for each individual.

A functional medicine model is an individualized, patient-centered, and science-based approach that empowers patients and practitioners to work together to address the underlying causes of disease and promote optimal wellness.

It requires a detailed understanding of each patient’s genetic, biochemical, and lifestyle factors and leverages that data to direct personalized treatment plans that lead to improved patient outcomes.

By addressing the root cause, rather than symptoms, practitioners become oriented to identifying the complexity of the disease. They may find one condition has many different causes and, likewise, one cause may result in many different conditions. As a result, functional medicine treatment targets the specific manifestations of disease in each individual.

We Are Different!

If you are on this website, odds are you or someone you care about is frustrated with their health! We do things differently here. This is not a high-volume clinic with a revolving door for patients.

Dr. Marquis’s unique approach assures his patients are:

  • Educated as to what caused their problem
  • In possession of a concise and well-defined treatment plan to correct their condition
  • Empowered with knowledge of what they can do to prevent or minimize the possibility of the situation occurring in the future
  • Initial patient appointments are at least an hour for and 30 minutes for follow-ups.
