Root-Cause Care
A deeper look at why you don’t feel well. Functional medicine studies how your genetics, gut, liver, hormones, nutrition, sleep and stress interact, then builds a plan to correct what’s out of balance instead of only covering symptoms.

How It Works
Functional medicine looks at your health down to the cellular level: how your mitochondria make energy, how your genes are expressed, how your liver processes hormones and medications, and how your endocrine system and brain are functioning.
Your plan focuses on nutrition, gut health, hormone balance, sleep, movement and stress, with targeted supplements to support healing. And because Dr. St. Marie is an internal medicine and osteopathic physician, it fits together with the rest of your care instead of running alongside it.

Testing
Metabolic, hormone, thyroid, nutrient and inflammation markers, ordered to answer specific questions about your health.
Testing that shows which foods may be driving inflammation and whether your gut lining is letting through what it shouldn’t.
A detailed look at the bacteria in your digestive tract and how they may be affecting digestion, immunity and mood.
A dried urine test that maps your sex hormones, how your body breaks them down, and your cortisol rhythm through the day.
A metabolic genetic test showing your tendencies in metabolism, cholesterol, insulin, inflammation, cardiovascular risk, iron, hormone pathways, neurotransmitters, mitochondria, liver function and dementia risk.
Members get lab work through the practice’s Fullscript and Quest Diagnostics arrangement at significantly reduced prices.
Genetics
Your genes describe tendencies, not a fixed outcome. 3X4 Genetics isn’t a hereditary disease test like BRCA. Instead, it shows where your metabolism, inflammation, hormone and brain pathways may need extra support.
That lets your nutrition, supplements, exercise and lifestyle be matched to how your body actually works, and gives you a clear reason behind every recommendation.
Getting Started
A short call to talk through your symptoms and goals and see whether we’re the right fit.
A thorough history of your health, diet, sleep, stress and prior testing, with a full exam.
The tests that answer your specific questions, not a one-size-fits-all panel.
A clear walk-through of your results and a personalized plan, with rechecks to track your progress.
Questions
No. Hereditary tests like BRCA look for specific disease-causing mutations. 3X4 Genetics looks at common variations that shape how your metabolism, inflammation, hormones and brain pathways tend to work, so your plan can be tailored to you.
No. Functional medicine works alongside conventional medicine. Dr. St. Marie is a medical doctor and reviews everything you take, including prescriptions and supplements.
The practice doesn’t bill commercial insurance. Visits are self-pay, superbills are available, and members get discounted lab pricing.
It depends on what’s going on. Some people notice changes in energy, digestion or sleep within a few weeks of starting their plan, and deeper changes build over months, which is why we recheck along the way.
